@mapman My man... you appear to be deep into Amir's well, no matter how hard you try to hide it. Just say it and be done with it 😂
there is only one way to find shortcuts when comparing products. That is of course to do the homework and understand what the differences really are. That ‘s what measurements provide.
I thought you would say "by listening" but, here you are...
And this, very bad analogy:
In a simple case analogy it’s how you decide what pair of pants will fit. You look at the size indicated which is determined by measurements.
Nope. It's by trying them on. This can be in fitting room at the store, or order a bunch online and pick the best AFTER you try them on. Say you are 36/32 on pants size. Are you saying any pants that are of that size would just fit you the same? 😁
