IRAY renders suddenly Finish in seconds without Max secs modified, why?

I get full renders even at close ups finishing in just seconds,  all of the sudden. IN Progressive Render section of NVIDIA Render settings, there is a Max Secs set at default 7200.   I didn't do nothing and now my renders finish in like 15 to 20 seconds and they look good. What in the world could have happened?
All i did recently is switch to Sun Sky mode   but then i switched back to Dome & Scene mode and i'm still getting fast renders.

I'm saying this because i thought IRAY was supposed to render up to the indicated Max Seconds and it's default is 7200.

You did not by some chance set it to render to 100% did you? That can cause it to freak out. I leave it set at 99.5%.
