Both engines will lift the same because thrust and power-wise, they ARE the same. However, heavier weight rockets, obviously, will not coast as long, so the 3 second delay is more appropriate. Lighter weight rockets will coast longer with that same amount of power, so they will need the longer delay.

So, for a GIVEN engine ‘type’ (A8, B6, C6, D12, etc.), the variations in rocket weight (all other things equal) are what determines which DELAY to use for that rocket. Something like a small Alpha might use the A8-5, whereas the larger Big Bertha will definitely need the A8-3. In either case, the A8 motor will be producing the same exact amount of thrust for each flight.

I hope that helps.
