Hey @tipu and @cardboard,
I undelegated 20 sp (by this account @replayphoto) and newly delegated 30 sp (by another account @refactory) just before, to see the payouts with no other transactions.
Does this make any difference which I didn't expect? I think I only changed account (and amount) to delegate.
Nope, it shouldnt do any difference apart that the second account will receive payouts now. You can check status to confirm the changes :)
