It feels like the gearshift debounce time needs to be reduced for most of the Formula cars in AMS. Particularly the Formula Extreme, V10, and Formula Reiza. For many of the corners you're able to brake so late that you physically cannot get down the gears fast enough to be in the optimal gear for the corner. And if you try and shift down too fast, then the debounce kicks in and you need to shift again. This is not a rev limiter-related issue as I let the revs drop significantly before taking the first downshift, it's definitely being limited by the game's shift debouncer (rejecting a gear change if it occurs within a certain amount of time of the previous change, primarily used to stop accidental double shifting). I'm not one of those guys who smashes down through the gears, but in this instance you really do need to be able to downshift more quickly.
