A couple questions regarding ICM calculations

I understand that ICM is very important in regards to FT and bubble play but how about during early or middle stages?
For instance say I get bumped down to a shoving stack around 1-15bb during the middle stages of a tournament, how do I know what hands I can shove or call with.

The way I see it and the reason for me asking is because if we aren’t near the bubble and I want to examine a certain hand to determine if my play was a profitable shove/call onto say for instance ICMIZER there is no way to take into consideration that fact that we aren’t in the money or at a FT, so I am sure our result will be skewed if for instance one person were to have a lower stack.
For instance I was going over a hand and I had around 5 BB and I knew the hand was a shove but because one other person at the table had 1bb it made my shoving range extremely tight therefore making it a fold (during mid stages).

So my questions:
How do I find out what is a profitable shove or call during early/mid stages when I get bumped down to a shoving stack.
Can I still use ICM to give me a rough estimate of what I should be shoving?

Any help with this would be much appreciated
thanks

If you are a long way from the bubble there won't be much effect due to icm. Although some small amount is always present it can often be ignored as it is smaller than the fuzz surrounding your opponent range guesses.

I think you can actually plug in a value for field size still left in to get a very rough estimate using icmizer (I don't usually use icmizer though).

Another quick 'fix' if you want to get some adjustment is to make a few dummy payout structures like 95%, 5% and/or 90% 10% and use these when inputting you hand. This will make a small adjustment if your table is perhaps 7 or 8 handed, perhaps this is a smoother way of giving an 'edge'.

Really though I usually just use chip ev and and try to make some small mental calc 'edge' adjustments but, like many things in poker, I think you need a bit of experience.
