29mm delay lengths

29mm  8 sec
FS   70
WS   80
SD   80
STD  50  D8=75
F    45
BLU  45
BK   40

45 = 0.45 inches
1d = 1.00 inch delay
1/32" per second more if longer, less if shorter

Buttkicker load (BK) with a 0.40" delay is 8 seconds
+4/32" length (0.53" total) is 12 seconds delay
-4/32" length (0.27" total) is 4 seconds delay

Generally never set a delay below 2 seconds since the 
delay also acts as a bulkhead during the thrust phase.
