i tried plucking rannars and the most i've gotten was 7. if its the same case with kwarms or w\e you planted, then consider yourself very lucky. Nah, you just haven't farmed enough. I think I can safely say I've gotten at least 20 or more 15+ patches, 3 patches that yielded 17. But I guess that's not a lot considering I've planted snaps since 88 or something :P
