I can try converting a CoCo cas file to wav, which creates a wav without delays, and try to load that on a real machine.

As far as I remember, I've done that with the Dragon and works well.

Maybe it works if the rom code stops the motor after the first block and then after processing it, starts the motor again and just takes the data in.

it's bad enough that most (all?) cassette formats fail to properly represent tape length, so most of the time side a and side b of the same tapes are shown as different lengths, despite being the same amount of cassette tape.

archival formats should not be stripping away delay / spacing / blank are data.

Certainly most these formats don't care about properly representing the tape, but as I said earlier, they weren't designed for that. The interest has been traditionally getting the program to work. For that wav files are the simplest solution (maybe CSW being close, but that already loses some info), but if the original media was flaky then the program becomes unusable even with an accurate representation of the tape.
