I saw many 1st ed fighters with 18/percentile Strength, but it was by no means universal.
Are we at data yet?
It's obvious that Hussar's original claim can be accurate to his experience, but was not universal. He was either hyperbolic or sloppy in his usage.
I saw plenty of OD&D fighters with less than an 18 Strength. What I didn't see (at least for long) was many with a Strength low enough post-Greyhawk to have a penalty (or worse, Con). If there were people who wanted to deal with that, they were thin on the ground. And this was a time when I was playing with a lot of different people over a period, usually as a GM, so I got to see actual character sheets pretty frequently.
This tells me that either people weren't doing the roll-by-the-book method (whether using some other methodology or outright cheating) or weren't playing every character they rolled (either by just ignoring them or swordbushing them). Given how often in those early days characters were moved from game to game, there was going to be no way to say which. Even characters that were primarily played in my own games I didn't try to supervise generation of.
