Zero Apnea using CPAP vs BIPAP Why??

I've switched from BiPap to CPAP these past three nights. I'm pleasantly surprised to have NO apnea each night.

Last night:

FL .6
OA 0
H .2
VS 1.9

AHI .2

Average Leak 19

AVG Pressure 10

Equipment: Respironics M Series CPAP Auto
Mask: CPAP Pro

I'm wondering if my BiPAP's timing of adjusting from IPAP to EPAP is such that it doesn't fully stint the throat long enough.

i.e. Apnea begins ==> IPAP goes to 15 on Auto then backs down to 9 EPAP while throat is still partially closed/closed.

On the M Series BiPAP Auto, avg setting is 9 and 12, also my titrated settings.

AHI is low, less than .8 most nights on BIPAP but still get nasty Apnea.
