Bump. Since feos asked me to translate my
post to English, I'll expand it a bit.
While this thread is about personal preferences in distributing 10 slots, I think that specific scheme is irrelevant to effective TASing. It's more important to learn mindless juggling with savestates. Not just use them often, but do it more often than common sense suggests. No excuse is needed to save or load a savestate.
The ultimate goal is to move savestating to motor memory and release brain for more diverse stuff like analysing game. When you successfully moved savestating into motor memory, you'll subsonsciently assign your own priorities to each of 10 slots (e.g. the easiest key to reach will become your most important slot, but you don't need to think about it, it should appear naturally).
I like to compare "savestates juggling" to how experienced pianist plays music - he doesn't need any time to decide which key to press, and he often performs a coordinated
sequence of presses (saving/loading many slots in a split second), without really planning it ahead.
When you use only one savestate slot and save/load occasionally, this would be the same as playing piano with one finger. I noticed some newbies use rerecords as rarely as in casual retrogaming, which doesn't produce good TAS.
From my old TASing experience I can remember entering flow state of mind and being able to do many save/loads within a second. Like this... ..Loaded the segment10, saved to1, advanced 4 frames, noticed possibility, savestate2, now Read-only, teleport to5, grasped set of buttons, jumped back to2, recorded some frames, saved to3, replayed from1, noted inconsistency, teleport to5, turbo to6, loaded5, loaded2, loaded5, loaded2, loaded5, recorded different set from 5 to 6, noted, restored6 by jumping to2, copy insight instead of buttons now, saved to2, noted success, saved to1, saved to9, loaded1, moving ahead!..
