yes, it was a mistake to only compete every few years. you show up, make an impression and the next year they are looking for you from the start.
odd, but consistent.
So there could be at least two reasons for that, that I can think of:
[1] You took three years off between shows in order to make improvements to turn pro [this seems unlikely to me, because I only ever hear about this for people who turn pro...not people who are attempting to turn pro.
[2] You weren't giving bodybuilding 100% of your time, or making a career out of it [I could see you picking up some sponsorships, but if you were making lots of money with it, I assume you would have competed more].
So if [2] is the correct one here [or possibly something else that I didn't consider], then we wouldn't know what your potential was...and I don't see it being impossible for you to have turned pro, given how close you were.
How well you would have done as a pro would have been a whole other level of hypotheticals, but I don't think it is such a big stretch to think that if you dedicated to competing every year, that you may have refined things to a point that you could have gotten a pro card, given that you didn't try this [so can't rule it out as being possible], and because you were so close to the pro level as it was.
Did you have pro level? I think so.
Did you have successful pro or Mr. Olympia potential? That's yet another level of hypotheticals as I said, so I won't answer that. You did have a few things in your favour - height, width, and vascularity, and probably some that I'm missing.
On Getbig, if you haven't won nine Mr. Olympia titles, you suck at bodybuilding.
