Very impressive. You'll excuse my inexperience. But if it was not a "bates
grain" set-up but rather a case bonded pour, shouldn't the burn have been a
pure progressive burn and not regressive? How's that possible to get a
regressive burn from a single grain (minus the pizza boxes of course).

This was to be the last test of this fiberglass case motor using case bonding
instead of segmented 'BATES' grains.Motor will be tested once more in two
weeks, Dec 19.
