Its nice to help others! I also manual vote every day like you do, but there may come a time when I use a bot. I have one set up on my Raspberry Pi but haven't used it.
Just remember that in one week, out vote becomes 4 times more powerful and it takes 1/4 as many to run low on voting power. 10 new votes will give as much as 40 current votes. Hard Fork 19 does this, as well as flatten the reward curve, which may boost our votes by a factor of 2 or so. Should be interesting!
Oh so there is a time set for HF19? The last I checked there wasn't one yet.
I'll be watching how my voting power does. There's another deal where the depletion in voting power gets less and less the more you vote because of how it's calculated. It's possible I may have to reduce my voting to 25% but only if I max out on my daily and weekly votes, which has not happened yet.

Yes, there are a few things that will change with HF19. Good day to closely monitor all bots. :-)
