Wondering how meticulous the illustrators were when they were drawing the Ironman suit variations?

I'm wondering if it is possible to for a person well versed in Tony Stark's long comic book history to identify which version of comic book Ironman's suit upgrades they are seeing just by looking at them in the panels of the comic books. How meticulous were the illustrators when drawing the Ironman armor detail variations as the suit evolved, comic book by comic book, over the decades?
