Hi, yeah, probably fairly useless, but not completely useless I think.
I guess all your teams are going to end up being fairly impressive, on aggregate expected to score between 350 and 450 runs per innings and take wickets at up to about 25 runs per wicket. They'll all be really good teams. And obviously I understand the fun is in the selection of the team, not in fine-tuning some formula to decide which is best.
But if you are trying to compare teams that are within broadly similar ranges, the ability to take 20 wickets has to be a factor. If both Team X and Team Y are going to score 350 runs per innings and concede 275 runs per innings, then the team that can bowl the opposition out twice is undoubtedly the better team.
To give an example, Cevno just listed his bowlers, who will take 20 wickets a match at about 21 runs per wicket. Somerset's bowlers will also go at about 21 runs per wicket, but his team will only take 10 wickets a match. Somerset's batting is much stronger, but it will be easier for Cevno to make up ground in the batting than it will for Somerset to make up ground in the bowling.
So it could be an indication separating relatively evenly matched teams.
That's all I wanted to say, not like it was meant to be the sole deciding factor. But it seems it has stimulated some discussion, which is cool.
