so if im level 35 and your level 38 driving I dont get profs? I thought it was the other way around if I was 38 and you are driving at 35 I dont.

i solo ~50% of my games, and i think prof faster.
that means 4h group prof < 4h single prof - but 4h group exp >> 4h single exp.

From my testing, soloing still yields more prof vs time than group play.

I wish I had the patience to solo. It's only fun for me to crank out a full group 1-71 lately.
Does duoing kill your prof as much as full group, or is it almost as good as solo prof exp?
Roy and I duo'd from 12-33 (rank 11 staff) and I got a little over 2% into my staff rank prof... I don't solo enough to compare.
A full group 12-71 got me like 4% I wanna say.

With my data, i can only compare solo vs group.

For easy math, lets say a full solo climb took me 6 hours.
The average prof gained per climb was: 2.738%.

During my tracking, my group climbs were about 2 hours.
The average prof gained per climb was: 0.693%.

6 Hours Solo 2.738%
6 Hours Group 2.079%
