1. 32-36 for utilt->grab. 36-52 leads to more utilts or uairs. 36-44 requires single step utilt, 44-52 needs 2 steps. I don't recommend 2 step utilts because when they DI behind there isn't a good followup.
2. You can tip as low as 38-42 with single step reverse fsmash. Key mixup to keep them honest with utilt DIs. On side DIs, low 60s is ideal. But unless they DI toward the edge, there are much better combo options to keep the chain going...if they DI the fsmash, you usually won't get any follow up and they'll stay at ~80% for ages.
2 (#2). They cannot shine out if you are correctly pivot grabbing. If you do not pivot grab, they can shine out as early as 16%. All you have to do prior to 16% is stand & grab on neutral/away DI or turn around on DI behinds.
3. Start pivot grabbing at 16%.
4. Dunno
5. Well if they don't jump you can go until like 50 lol. But effectively, you should look to end your chain grab and utilt at 32-36.
6. 16%.
7. 6%.

I listed Fox numbers for all answers (except #7). Add 8% for Falco, as a rule.
