Well, for me i actually calculate them ==
like if my water uses about 270sp per battle, 1 battle use about 1 G.syrup.
1 hour = 60 minute. lets say IF 1 battle last for 1 minute. 60 minute = 60 G.syrup
if i afk about 10 hour, i leave 12-15 stacks [10(hour) x 60(syrup) / 50(a stack)] [sometimes more, just to be safe].
well , until now i haven't once ran out of sp supplies during afking...at lest not yet ==
