Just trying to do a bit of “maths isn’t scary really it’s just describing the world around us”. May still be in maths teacher mode form my kids exam revision sessions.
No offence meant regarding xg stuff. It's just that I'm starting my 62nd year of watching the city and football in general. (I'm now 72) Never have I, or anyone else I know, have ever bothered with these sort of statistics. It's the same watching a game on tv. I can't be arsed knowing how many touches a player has made or what percentage of the ball play a team has had etc. I just want to enjoy the game without the waffle and constant showing of ( to me), meaningless statistics.
Anyway, rant over. Enjoy the rest of the season. It's been an amazing start! 😉

Big Chance just meant over 1 in 4 chance of going in. It’s totally arbitrary.

Apparently Sakamoto had 0.7-0.8 xG over two chances v Hull, one chance being over 0.5 xG… I can’t recall 2 such chances.

It’s not an arbitrary measure, there’s clearly a mathematic formula behind it.

Been out all day at a bbq and missed the match (doh !!), but followed the game on my mobile via goal alerts.
There were so many of those, that my battery almost died lol
Just watched the highlights, and to be honest, we could have had 10, due partly to our great play, but also QPR's awful defending.
My thoughts :

-Top scorer last year was Wright (striker) with 12.
At this rate, we could not only have a couple of strikers beating that, but we could also have 2 midfielders with more than that as well.
That's extraordinary really, and makes you wonder how insanely valuable, Frank's midfielder knowledge and experience is.
Both Rudoni and Torp have improved immeasurably under Frank, Joe, and the coaching team.
Torp's 2nd goal today was filthy.

-Matt Grimes for £3m is looking like an absolute bargain.
He looked like he controlled the game today, with his usual understated style and coolness on the ball. He's such a good link player between defence and midfield. I don't think there's a better player in his position, in this division.

-BTA is improving, game by game, and surprising many of us. Keep it up BTA (y)
Excellent goal today, and used his immense upper body strength, to set up Wright's 2nd goal.

-And finally...the club and ground are reunited.
That's something i didn't think i'd see again my life time (i'm in my 50s)

I have to say, DK has done a cracking job as owner, even more so when you compare him to the inept SISU clowns who owned us previously.
How can one owner be so bad, and another be so successful (so far at least) ?
The main concern in my mind, is whether DK sticks to his 5 year plan and sells up...in which case buying the stadium is a smart move, as that asset (when added to a successful team), will greatly improve the club's value, and be attractive to a prospective new owner.
Or will his (so far) successful time at Coventry, turn him into a real fan, and encourage him to stick with us.
Personally, based on his record so far, i'd want him to stay, due mostly to the numerous squad and infrastructure improvements that he's instigated.
He also seems an honest and likeable chap.
New wealthy/foreign owners sounds great, but they don't always work out well...just ask Wednesday fans.
Well I'd say it was a classic example of after conceding the first,still going for it, not very well though!

It’s a proprietary formula is the problem. Some companies account for defender positions some don’t. Some take their baseline stats from similar leagues some don’t. And we don’t know which is which or what a site is using. But the general theory is sound and it clearly helps scouts and has some level of predictive power.

I don’t think yesterday is an example of xG being wrong, our first dive shots on goal all went in. One was massively deflected, we hit an absolute screamer for one second half. Their keeper had a proper mare. It doesn’t take away from us, but in another game with and other keeper it could easily have been fewer goals and outside the goals we didn’t create lots of clear cut chances that we missed. We romped to 5-0 up with our first 5 shots on goal and took it pretty easy second half.

xG rarely works when one of the sides has a GK the quality of Wilson or Collins.

It's a mathematical model but the inputs are essentially one systems viewpoint. I guess they use a feedback system to try and refine the model but like all models the parameters are what can be measured and there are things that can't be measured like for instance a player's state of mind and whether or not they're carrying a niggle.

Not only that there are different models out there so not all xG's are equal. 😁

Also the idea of applying xG to one shot is like saying today's temperature reading is an indicator of future climate trends.


Anyway 🥱 I'm like @Houchens Head I just want to see the game, I have no pretensions of being a football expert, I can state my PoV and people can take it or leave it.

Next game tomorrow innit.😁

Im impressed even in an xG discussion you managed to get some random climate skeptic nonsense in there.

You may not believe in maths, but luckily for you the designers of your cars and airplanes do.

You are so easy to trigger. 😁

Torp can shoot on target too, unlike sheaf! Take Torp out and you’ve instantly lost a goal scoring threat
Torp can also pass the ball forward.

Many is the time ive lost count of the number of sideways and backwards passes Sheaf has made.
Im not saying Sheaf isnt a good player, but there can be no doubt that we are more dynamic with the current 3 midfielders.

And as you pointed out, Sheaf cant shoot for shit.

I think “everything we hit went in” is a pretty accurate story of the game tbh.

Correct. There’s actually a very good explanation in The Athletic article yesterday - in short, it was a freak. It was the 3rd largest discrepancy out of over 18600 games across Europe where xG has been recorded. The top 2 were also 7 or 8 goal thrashings.

Cannot get ‘LA LA LA, LA LA LA LA LA’ out of my head.

My partner just asked me why I keep humming / randomly singing Kylie Minogue.

I did explain, even if she didn’t seem to care!

I'm a big believer in the usefulness of xg but it does feel like some of our chances were undervalued. BTA's goal was only valued at 0.27 despite being an uncontested shot from basically the penalty spot with only the keeper to beat.

QPR have also signed 3 half decent players since we beat them lol

I find the stats interesting but at the same time find it all a bit American and I'm not sure a game or players can be evaluated as easily with stats as bland Yank sports. I guess when scouting it can help bring you to a target but you'll still want to watch with your eyes.

The stats do tell the story of the game. Anyone watching on Saturday, it felt like we were going to score with every attack and we more or less did. Our final 3 of our goals were all low xG chances.

Even if our xG was double, or triple the figure of 1.27… it tells the story that we were efficient in front of goal. Most 7-1 results are anomalies to some degree.

I have wondered how xG is compiled.

Is it done solely on the position of the shot because I can't see how they could get an accurate like for like comparison.

For example you could have a shot from say the penalty spot but be one on one with the keeper and the ball sitting perfectly for you and another from the same place but with three defenders in front of you and the ball bobbling and slightly behind you. How do they allow for those differences?

Also, what is it compared against? Is it just similar chances in your own league, or every league and if so how far does it go? A chance with a player at a higher level is probably more likely to be scored than at a lower level who have poorer technique. If it includes everyone teams higher up probably would have a lower xG than is accurate while poorer teams would have a higher one.

I think it can be useful but it has to also be flawed.

Some bedwetters on here were quoting QPR as having done good business in the Summer before the season started, quoting them as an example of what we were missing out on and should be doing. Just because they've signed more players doesn't mean they will be any good!
