Oooh man - if "your Stealth Power > Opponent's Evasion Power" is right - that will put a huge dent in my Opponents Stat Table spading. Testing opponent's Evasion is ten times more difficult than testing any of their other stats for many opponents. [Otherwise need to do enough damage that you hopefully see the whole range of their evasion range, and that their relevant attribute is larger than their evasion+base power (or otherwise notice that it's capped); and for techniques that only come up occasionally or have a large range you either end up not doing enough damage to test it or end up killing the opponent too quickly.]
