If anyone's interested, I've done some more number-crunching - thanks to GoS, as usual - though I'm not sure it tells us anything we didn't know.
I looked at the results for the last 10 seasons and compared average points earned per evening game with average points earned per weekend game (league games only). To put it another way, I calculated as a percentage how many of the available points we picked up.
- Evening games at home outperformed the home game average in only 3/10 seasons, i.e. our points per game rate was better in weekend home games in 7/10 seasons.
- Evening games away outperformed the away game average in 5/10 seasons.
- Away evenings outperformed home evenings in 5/10 seasons.
- Home and away combined, weekends outperformed evenings in 7/10 seasons.
I don't know if this adds anything to the dark/light shirts argument. Given that most away games are played in a lighter kit, the fact that in 5 seasons out of 10 we were more effective on home evenings isn't an argument in favour, but then again we would expect to lose more away so maybe 5/10 is quite good.
