Calling ranges

Seriously, not to be rude, but haven't you been around long enough to know that you can't just come up with a list of hands to call pushes from specific positions? These kinds of questions will never be answered in the way you want them to. It depends on more factors than just the open-pusher's position.

Standard answer is: Post hands were you're not sure what to do, and make sure to include reads, stack sizes etc. Then you can ask "What's my calling range here?".

Well I do know that it's not that easy to say so what are some general thoughts that go on in your mind before you call. What calculations do you use?
I mean you can put him on a range and calculate the equity against your range but do you constantly risk half your 20BB stack if someone with 10BB shoves and you have 55% equity against his button shoving range.
