A tweak to the review system. There are three decisions: out, not out, and umpire's decision. If it comes down to umpire's decision, the team appealing should not lose one of their referrals.
But if it is a marginal lbw, it's not a bad decision to refer it, yet you lose another referral. I agree that, as with that one, where it's shown just to be skimming the stumps, it should be left as umpire's decision. I just don't think the side referring should be penalised.
I've thought this before, btw. It's not just sour grapes.
The current state of the match is still very much within the margin of luck, which is a phrase I have just invented.
