Board Game Arena

Is there away to count game progression not just by points? I mainly play 1v1 games. Its really frustrating when after 15 rounds oponents sees hes about to lose and quits. And i get 0 elo for playing 15-20 rounds. Makes no sense.
Can you also count game progression by turns? Say 10-15 turns are 50%?
Extra elo loss and Karma loss is a very small fine for wasting other people time
