can i know use of the "Progress to next payout: 0.63637910 / 1.30020000" ?
i think it wasnt explained in FAQ why is it there. so if it doesnt reach 1.3 the next person in line doesnt get paid ? and move to next person ?

That is the amount of funds the wallet has against how much is needed to pay out the next in line + fees (5% +minerfee)
If the countdown for that user expires and the wallet doesn't reach the payout threshold then yes it would move to the next user.
