Assignment servers should really have a rule to assign big work units to GPUs with high shader count first, so Nvidia RTX 2080ti or AMD Vega don't idle 50% on small work units.

Seems like in the case of 2080Ti the increase is well over 35%.

The AS already has such a rule/preference that is in place for the higher end nVidia cards, they are in a different classification within GPUs.txt. There are smaller GPU projects that only get assigned to the higher end cards if no others are available.
For the AMD cards that may happen in the future, GPUs.txt is still in the process of being updated to separate out the AMD GPU's that are incapable of DP processing. Also a new class was added for the Navi based cards that AMD released based on their new RDNA architecture. So far we have been provided the device ID for the 5700 XT, 2-3 other cards have been released.

The QRB formula is not linear, faster cards will see a greater increase.
