Hi Envoy!
So first I want to explain that between the mandatory upgrade (that we believe fixed our prior syncing issues) and the upgrade to the new pool protocol (v2.0 in 1.4.4.4) the older miners will need to upgrade to 1.4.4.5 within a few more days, as soon pool.biblepay.org will increase its minimum required mining version. This new version will allow more flexible configs and more accurate health reports.
As far as the exec bankroll, the newest versions (1.4.4.4+) sends out more denominated change, but only in GSC created transactions. So you actually have to be in POG or Healing or Cameroon One to get the benefit of automatic change. For example, if you tithe 2.50 in POG per day, the wallet will send back change in 10 bills - meaning you wont have to create bankrolls.
If your miner only heat mines, you only have to create the bankrolls every so often~ after the initial bankroll (as the wallet will pick the minimum amount of coins for a new abn). But yes you would have to keep an eye on them manually so they dont all get used up. But in general, if you have 10 200K notes the abn creator will use the least and you will still have 10 after you get the change.
Thank you for your patience to answer questions.
My machines all update to latest version now, and will try to use POG later when I have a time to test.
Thanks and God bless you.
