All very good points.Careful here, if you are using this information to determine if you should raise or not. If you're considering raising, not calling, then you need to run your equity against the range of hands he continues with after your bet. If he's folding the worst of his range, it is possible that you won't have an advantage anymore.
Also, a 51% showdown equity (which is what the calculators show) doesn't mean calling pre-flop is going to be instantly profitable either. You have several streets left where more money could go into the pot and where you might be forced to fold. Certain hands will have a harder time realizing their equity when out of position, especially if your opponent is aggressive.
I wasn't exactly trying to go too much into it other than just think of ranges and not just a specific hand, but that's for taking it further.
