I think powering up 100% is the maximalist's strategy.

Huh I just calculated with my formula from yesterday and you're right! It increases your net author reward by around 1.2%!

25.303*0.601=15.207 or 99.5% proximity to expressed value ($15.283)

whereas my last post is 96.6% on a hive+hbd calculation, and it would be less if i only got hbd.

I did this calculation years ago and it was the opposite, full powerup giving less rewards than other combinations. It seems things have changed.
