Thinking about custom structure

My best guess is that since Segments 2.1 and 2.2 are essentially 'skipped,' then we would assume that the projector expects two junk audios before playing the 'third.' Perhaps one could get away with minimizing Segment 2 while completely removing Segment 4, but keep the addresses all just either the final byte after the audio, or maybe the beginning of any Region?

This would the put our time-capacity estimate at the following:

p25d80sh flash = 1048576 bytes
Segment 1 = 108 bytes
Region headers = 6 bytes each
Segment 2 must be minimized
Segment 4 can be deleted
Minimal packet of audio = 10 bytes (20 ms)
Each byte = 2 ms audio

$1048576-108-(2*(6+10))-(12*6)$

= 1048364 bytes

$1048364/1000=1048.364$

= 1048.364 seconds of audio

$1048.364/60=17.4727333333$

$\approx$ 17.5 minutes
