I don't think it is logical to try pos with current ratios.
I am not going to let my pc open for days just to get 2-3 sirx.
At the least I think it should have cumulative stakes. Run the wallet for 12hrs one day and another 12 the next day would be the same as running it a full day towards rewards. How things are now you lose any time put in if it isn't 24/7 before hitting a stake.
