I am using 48 cores for ECM work in 320000-360000 range with a major goal to complete all unfactored <500000 to 30-digits level.
4 more cores are working on numbers with known factors in 10000-11000 range.

Right, That´s a considerable amount of computing power. Hope you´ll find many more factors along the way .
I´m working a bit further up: 600k and 800k, also with B1=250000. My success rate has been rather low, though, which is normal considering I have only 8 cores at it, and four of them belong to a 10-year old i5-750

For now 15 factors was found in ~130 attempts.
Good luck to you, too.

Please tell me you are using GMP-ECM for stage 2.

Yes, that is good advice. For such small exponents there is a lot to gain. One of these days I will resume my "sub 10K" crusade and then I'll be using GMP-ECM once again.
After all, there are just 64 left to factorize... LOL

I plan to do so but not yet. Will I need to email you the results in this case? Or there is some way to submit it using manual testing results form?

You will need to email me exponents, curve counts, and bounds. Later I can show you how to use the manual forms.
