When reading about range analysis in books and looking at range analysis tools online it always seems that the ranges are not weighted, is there some reason for this?
What I mean here is that say someone opened from UTG, we could say he has a narrow range. In a book they would then say that his range is something like: 99+ KQs+. If we then do an equity calculation against this range we are calculating our equity against these hands and saying that they are all equally likely.
Why do we not consider a weighted range, so we would multiply the equity against each of these hands by the chance that they are playing that hand this way, this would seem to me to give a much better result?
Thanks for any help
