This is a very, very unoptimized run for a category like this, I'd go through every unoptimal segment in this movie, but the post would be about 3000 words, so here's a snippet from stage 1 and 2.
Since this is a TAS, every nonspell and spell card should be timed down fully to 0 for extra graze, as the spell card bonuses do not matter when compared to how graze works.
Graze in Touhou 11 affects the Point Item Value Multiplier, for every 100g, you get an extra 0.01x point item value. A rough estimate of the item count for a NoMiss NoBomb play of SA is going to be about 2,150. It could be a bit higher than this depending on 4midboss kill technique, but let's just assume that there are 2,150 items in the game, shall we?
Stage 1 :
Already we're off to a very unoptimized play; the WR by ior gets 2,960 Graze after Kisume (stage 1 midboss), while scratchtas gets only 652.
With some rough calculations, we can estimate that the score loss from this is a massive 80 million points, already. (2110 * 200,000 = 422m | 2110 * 200,000 * 1.2[graze multiplier change] = 506,400,000)
Entering Yamame, Ior has 4,070 Graze, and scratch has 1,328. A difference of 2,700. Mind you, while the two categories are different (One is allowed deaths and bombs, the other is not) The two runs routes are identical to this point, so this lost graze is purely the result of very poor optimization.
On Yamame, Scratch also just doesnt time down anything. Opting for spell bonuses, which is so completely not worth it it's not even funny. Spell 1's bonus is 3mil, while the score you would get from timing this spell down fully is approximately this : 2,020 * 200,000 * 1 = 404,000,000 | 2,020 * 200,000 * 1.06 = 428,240,000, so the score LOST from going for spell bonus is 25 Million points.
Non2 is also killed asap, you can just estimate the score loss if you want. But once Yamame final begins is the final time we can compare with ior. Ior will bomb the 2nd wave of the final spell, and their graze difference is 4,800.
Stage 1 alone shows a lack of care for maximum scoring, but let's just continue through the rest of the game, comparisons to Ior from this point on will no longer be around, as the route will differ. But I'll do my best to estimate a score loss at the end (if I bother to look at everything)
Stage 2 :
The grazing on the yinyangs before the midboss are very poor, losing chunks of points as you usually will want to let them fire everything they can before killing them in a TAS. Let's be generous and say 350 graze is lost here. (350)
The yellow/green yinyangs are also killed instead of stalled for graze. (850)
Parsee non1 is instakilled (1,850)
Same for spell 1 (2,850)
And non2 (3,500)
Spell 2 doesnt even do the scoring strat. (5,000+4,800)
This feels more like a speed run than a "scoring run" due to how much score is just lost from a lack of actual scoring.
The rest of the run also features millions of points lost at every attack in the game, I can't really be bothered to look at the rest of it from just skimming stage 3.
Notable exception is Stage 5 boss, Orin's 2nd nonspell where he misses out on like 50 point items aka 40 million points at the very unoptimized graze count at this point in the game (and when we add the 10,000 graze lost in stage 1 and 2, this score loss jumps to 50 million, let alone the rest from stage 3,4 and 5.
