Can't Figure Out More Triggers Ratcheting

[mgd]

I've tried two versions:
1)

Code:

ROW    T3              FX1          FX3
00     40
04     40
07                                  PRF1 064
08     40              TR3 0C3
0C     40

2)

Code:

ROW    T3              FX1          FX3
00     40
04     40
08     D3              PR34 024
09                                  PR34 064
0C     40

All other cells empty.

Version 1 IMO should work but does not and I'm not sure why.
Version 2 works (kind of) except for the fact there's either ratchets or nothing (which could be catered for by another lane that always sends a trigger and than OR the two but again that shouldn't be required).

Maybe Thomas knows why Version 1 does not work.

Kind regards,
Michael
