Based on what you've written, No. But really it depends on the curve in the distributor.
Look at the timing graph I posted above. Notice the CAP distributor is set at 5* After, while the other at 5* BTC. Yet they end up at pretty much the same place by 1400 rpm. Now lets say you've got the original CAP distributor; setting the initial timing at 5*BTD at 550 rpm is 10* more than spec. This will will add 10* everywhere and it will ping under load.
