Set your multiplier to give the h-e vote you want to get when you vote your normal hive percentage.
I normally vote 25% hp.
I set my multiplier to 10.
I give 100% h-e votes on 10% hp votes and higher.
I set the multiplier this high so that I have flexibility in how much I want to give in hp.
The code won't give more than a 100% vote under any circumstances and if I want to give less than 100% I can just lower the hp vote accordingly.
