Well, how many strokes does it take to hone a razor on say norton?
It somewhat depends on the person honing it, but my understanding is that the experts all use a similar amounts.

So, it seems to me it's possible the stropping depends on the person's technique as well.

Now there's an easy way to find out and unfortunately this thread should've come up a week earlier. here's my proposed experiment

Take a honed razor and two stroppers A and B, A needs 5-10 laps to get the edge as good as they think it can be, B needs 50-60 laps.
* A does the 3-4 laps and they both evaluate the edge at this point.
Then A does 3-4 more laps and they evaluate the edge again. Then A does another 5-10 laps and they make a final evaluation. According to A the changes happened between the first two evaluations and nothing happened between the second two evaluations.
* They should be able agree whether there has been an improvement or not (or at least a difference) - a hair cutting test may be fairly convincing if there is a difference.
* Then B proceeds with 50 laps and then there's a new evaluation of the edge. Potentially adding an evaluation at the 25 laps mark, to judge if the edge changes at all after it has been deemed final according to A's procedure.

* Then take another honed razor and start with B performing 25 laps, evaluate the edge
* Then B performs another 25 laps and evaluate the edge again. At this point the razor is as good as it gets according to B
* A can then proceed to strop an additional 5-10 laps with potential strop in the middle to check whether there is a change to the edge after it's been pronounced 'final' by B.
