not the answer you're looking for bunky but the whole "extractor sector" most likely amounts to the numbers put up by the top two we all know and love.
So IMHO the valuations you are looking for are most likely whatever they calculate them to be after they uplist and post the next 2 Q's. That should be the 'REAL' gauge you are looking for. Figuring in the all-so-rans of the sector to find a 'median for the group' would most likely skew the numbers which would surly reveal the 'best of breed'.
Sorry for no real help bunky, but I feel this is an unusual situation where 2 companies are so far and away leaders that they may run away and hide with the goodies....for good! Can't put a number on how exceptional they are at their craft...not yet. But the '27 Yankees, Tiger Woods 82 victories and the 21st century N/E Patriots have nothing on them.
Sitting out on a limb here possibly sawing it off behind me but hey!..nothing is ever a sure thing!
