<SPAN class=postbody>How many chips are needed when looking to make a +Cev decision?

For instance:
I have 4500 chips with blinds 150/300+25.

I'm at a very loose table in LP where raise folding is -99 chips.

Raise calling is +18 chips if I'm 41% vrs. villians reshove range.

So I understand I can RC with hands like 22+,A5o+,Kto+,QJo+,A2s+,K9s+, and on average increase my stack by 18 chips.

Is gaining 18 chips when I have a 4500 stack worth it to make this raise call?

If it's not enough chips at what point should I look to make this RC?
