Thanks for the answer. I'm staking 5000 split up into inputs of 50 at the moment, staking about 1 GP every 3 hours which works out about 0.1%/day or 3%/month.
I've pretty much decided I'm in for the long haul so if it would actually improve the staking I'd be happy to sink a couple of hours splitting up into inputs of e.g. 5 coins. I've done it before for another wallet where the stated rules were "as many inputs as possible". I suppose 1 GP inputs is a little low since with a fee of 0.2GP you're losing 20% of your coins to do that.
Another point I was considering was - at the moment I am getting 1GP rather than the stated maximum per input of 2.5GP. SO perhaps I should INCREASE the block size so that I gain weight more quickly, and stake close to the maximum of 2.5 per input.
So my 2 questions are
1 - will it improve staking if I split up into even smaller blocks like 3-5GP? Or should I increase the size of the blocks until I'm getting near-maximum stake rewards, like 2.4GP per time?
&
2 - is there a way of using coin control or anything to split the inputs, or do you just have to send them to yourself in lots of transactions?
Thanks again
