I was going for Streets SA 1:56 this past week and watched Goose's tutorial. In the tutorial he mentioned the cutscene offsets being 0.75s for the 1 guard cutscene and 0.85s for the 3 guard cutscene added onto the timer calculation (switch + end).
My question is whether this offset actually is 0.75 and 0.85, or if these numbers are rounded. Considering the game runs at 30fps, should this offset not be a whole number of frames?
The reason I ask this is because I decided to analyze a bunch of other people's runs to see where I was most in need of improvement. I wrote a spreadsheet and input a about 20 of other peoples' SA and 00A runs and compared several different metrics. In doing so, I analyzed Mike Mint's 00A 1:54 and with a 3 guard cutscene (0.85s), a 214.66 switch and a 451.18 end, I actually came up with a 1:55.01. If the cutscene offsets however are a whole number of frames and the real offsets were 0.723 and 0.823, then his run would calculate to 1:54.993. If this isn't the case, then his run must have had some other partial-frame effect or rounding that doesn't usually need to be accounted for (technically if the quoted offsets are correct then there MUST be some partial-frame effects because the offset itself contains a partial frame).
As a follow up question, are the the quoted 0.75s and 0.85s cutscene timings actually the PAL cinema timings since PAL runs at 20fps (0.05s per frame)?
