I think CR31 just maps over the whole range of the card, so for a card with a more powerful amp, a particular CR31 setting relates to higher power output than it would on an ordinary card. With some cards setting CR31 too high can give a distorted signal and increase out-of-channel radiation (some references if you google for WAP11 CR31 e.g. http://www.maokhian.com/wireless/wap11.html)
