Last Friday I checked mode matching without parametric amplification of BAB and it was 95%. Today I checked mode matching with parametric amplification. Pump green was 40mW. Mode matching was 95.4% as follows.

After this measurement, I checked mode matching without parametric amplification. Though IG20 was too small to be measured, mode matching was 96%.
