As all the blocks are competing against each other to get one of the 960 stakes a day, I am unable to figure why 1,600 HYP is the optimal size block.
It is optimal under the assumption that you stake every month. Then, the interest you get will be around 1000 HYP, and so not clipped by the max subsidy.
If you keep larger blocks, but open your wallet more often, then you can keep larger blocks and still not get your interest capped.
If you were to stake after 10 days (so, 1.2 days after the shortest time posssible), you could keep blocks of 4500 or something around that value, since you'll get maybe 20%-25% off that, which is almost 1000. But you get clipped if your block takes a while to stake (and as difficulty gets higher, it tends to go that way).
I've set my wallets (I have 2) so that they're constantly open, in the background, so that I never miss the opportunity for staking.
That now makes sense.
There's going to be people out there who simply don't keep their wallets open.
So when someone has a block of 1,600, and opens the wallet again after around 30 days, they'll get around 1,000 HYP in interest, but no more.
For people like me who leave it open all the time, that' not going to be an issue.
So from this, I can pretty much conclude that if:
- You leave your wallet open 24/7 - have a larger block size, to help with your staking weight.
- You open your wallet once a month, keep your blocks around 1,600 HYP.
