After a few troubles (here) i completed richter speedrun using the optimal route
Noone realy excepted that outcome, but well, here it is! Richter beating maria :p
The main reason is obviously the unskipable dialogue you get when you rescue maria, and also the reset needed to select her
It was originaly tought maria would beat richter regardless, this is why the first submission was more oriented on entertainement than pure speed (stage3/4 been more interresting than stage3'/4')

This run use a few cool tactics to save time, the main time savers are (abuse off) the key subweapon and the flipback

The key subweapon is obtainable in stage2, this is why i dont go by stage2', the key damage output is twice of the whip, it cost zero heart to use, the item crush (select button) is also "free of charge" (altought its completly useless)
Also, on most bosses of the games, the key is not "nerfed", a regular axe does same output than key (16 damage), but most bosses have some kind of "protection" that reduce damage, the key was probably overlooked in most cases and do full potential (6 hit and boss is dead in most cases)
Unless proven wrong, stage2' route is slower due to using regular subweapon and needing to collect hearts all over the way
Obviously the key was just meant to be used to open doors (maria & the other girl in stage7), not to be a weapon, i use item crush a few time for entertainement coz on first submission i was told its bad not to use it, in stage6 it does roll the boss rng pattern i dont use it just for style (note that the youtube encode will show more key crush than the real movie does

The flipback save time over walking, i dont know exactly how many pixels, i think it doesnt realy matter, but just in the first stage - first room i remember i saved several seconds over walking, so its common agreement that walking is wrong for speed purposes
The idea is generaly to cancel your current flipback as fast as possible, so you try to make the shortest flipback possible, to cancel the "landing" kneeling effect you need to use an attack
The key was a great help over the flipback, first of all it doesnt make sound, so basicly i didnt ruined the audio experience of game by having a constant flipback+whip in the whole movie, only stage1/2/7 use whip, stage3'/4'/5/6 use key for flipback
The real reasont the key was technicaly superior for flipback is the pattern been much more simple and not realy impacted by hitting something on your way since its realy short range
I will try to define more precisly how the "loops" for flipback are working later on

Stage by Stage Review

For latter ! plz be patient...

Frame compares with regular stages route and maria

Just a little comparate between the 2 movies, measured with time spent on given stage from first image to first black screen after end stage score
Of course this run use the alternate stages (' or prime) and the old one use regulars stages, so its just for reference i put theses, maria is somewhat mixed in between, her table is just to show shes faster, she loose because of the dialogue but in most stages she do fine (i didnt compared stage3 since they are completly different)

Stage Old run This run Frame Gain
Stage1 6639 6617 22
Stage2 9254 9397 -143
Stage3/3' 8436 5892 2544
Stage4/4' 10007 7802 2205
Stage5 9740 9148 592
Stage6 7933 7892 41
Stage7 9827 9594 233
Stage8 4244 3755 489

I made some improvements obviously in stage5/7/8, for stage6 ill guess frame rules, its basicly done the same way

Stage Maria This run Frame Gain
Stage1 6652 6617 35
Stage2 15295 9397 5898
Stage4' 6545 7802 -1257
Stage5 8662 9148 -486
Stage6 7706 7892 -186
Stage7 ???? xxxxx xxx
Stage8 ???? xxxxx xxx
