Match is of course a better grade than Club and goes through better quality control than Club, so each round should be more consistent compard to the one next to it. It also has the patented EPS nipple which punches a cleaner hole in the paper.
You've fallen into the trap of thinking Match is Match is Match.
If you look on the end, there should be two lines of numbers. The top one is the batch number, the bottom (four digit) number is the speed in fps. It's normally somewhere between 1020 and 1080.
Eley deliberately vary these because some rifles like fast ammo, some like slow. It's to do with any number of factors - barrel length, weight, harmonics, crown condition, wear on the rifling (ok, the last two will affect all ammo, but some speeds will deal with it better than others).
If you were pushing for the upper echelons, you can go and batch-test Tenex at Eley's factory. Anyone can do it, it costs about £40. The results are remarkable. With a batch that really doesn't like your barrel, the groups barely hold the 10-ring at 50metres - and this is with £7-8/box ammunition! On the otherhand, the best one or two batches will group inside the inner bull. It's not to do with the quality of the ammo, it's simply whether it works well in your barrel.
Since I don't imagine you want to worry about the expense of formal batch-testing, I would suggest you try and acquire several boxes with different speeds, benchrest the rifle indoors and work out which speed ammo it seems to like. It doesn't need to be an exact science, but if you can go into your dealer and say "something round the 1055 mark", or look at a box of 1080 and say "nah, that's a waste of time for me, got anything a bit slower", then it may help your scores.
Some batches of Match or even Team will shoot better through any given barrel than some batches of Tenex. Ultimately if you sorted out the best batch of Tenex it should be a world-beater, but the price of the ammo does not mean it is the optimum ammo for your gun!
Money can't buy you better scores, and having the best kit won't buy you medals - some people get very hung up tweaking their kit when they should just get on the range and shoot - but that doesn't mean you shouldn't spend an afternoon finding the best combinations of rifle and ammo so that you know when you're doing your job the rifle and ammo are doing theirs. We assume that if we point the rifle at the middle the shot will go in the middle, but the truth is that simply slinging random ammo into a random barrel (even really good ammo into a really good barrel) can produce wildly variable results. It's no good if you spend £500 on ammo which (in your barrel) barely holds the 10-ring - you can shoot a technically perfect shoot, but the shots will be going out because they're not going where you're aiming them.
That said, even if you don't have time for that, I would go with Match or Team above Club for the EPS nipple. The clean hole it gives can nudge many a marginal shot inwards when the tears in the card formed by Club or lower would have had the gauge fall out.
Tenex is a waste of time unless you've batch-tested. Team and Match start out life trying to be Tenex and are graded appropriately when tested for consistency. Shooting a random box of Tenex is the same as shooting a random box of Match (you're just paying £3 more a box for the privilege!).
