Hey, you are right. i'm not even close. i had Maggie 6, winona 3 and anya 1.
Since then i have always done the reset around end of twins / beginning of maggie, because i have to wait to long for the skills of maggie and winona (and the last 2) my skills are on all the time... i know the skills i need and the last few hours when everything gets too slow i check which one i can still complete within the timing of the standing filming times (stamina) all the rest of the skills i stop. (like trick at 40 and artistic at 42) so i can let more girls train their skills.
