Had few days off work this week, so decided to stop being so lazy and actually put some work into my game - Early NY resolution

I've been carrying out some EV calcs using a Shove Equity Calculator and although I have nice result telling me I make X amount of chips by shoving all in I'm trying to work out if the gain is worth the risk (of potentially busting). Is there certain '% add to stack value' that people generally use a guide in these situations???
I appreciate that just because shoving maybe +EV it may not be most optimal line, but imagine there must be apoint where you add so much to stack that its a no brainer?!
For example if my Net profit on average is 2000chips and I have to risk 20000 to realise that, is 10% gain enough to justify sticking it in??
Maybe relevant, maybe not but does the Villians expected gain have any correlation to this question?? (the tool I am using gives a value for hero and villain) - So if hero EV is +2000 chips and villians EV is +3000 chips is that giving me the answer I need?
Any help appreciated... Ta
