Geez IDK.

If you can track stand for a whole light sequence, even with a little creep, I don't really see what your problem is?

How long do you want to do it for ?

I can do it for a pretty dang long time , standing usually tho, but I might creep a tad as the stand goes on and on.

I don't think there is a trick to doing indefinately, its just a skill like juggling. I can do that to but I doubt I could break any records.
