2 inches is a good gain, but comparatively modest in the LL field. You went from 35th percentile to 60th percentile in the US. In a room of 10 other people, you used to be taller than 3 and now are taller than 6. Had you gone for an extra inch then you would be taller than about 7.5 people's, about 8 other men out of 10.
You started at a nearly average height, and still went to a nearly average height, just slightly above. That is perhaps why you feel dissatisfied.
The major reapers of LL are those who went from very short like elementary schooler kid short to within standard distribution (5'1 to 5'4), very short to nearly average (5'5 to 5'8 ), and average to the objectively "tall" percentiles (5'9 to 6'0)
You went from average to average. I find it highly worrying that your height neurosis hasn't been cured, especially after all that effort. I fear you may retain this neurosis for a long time, and perhaps you may go back for Tibias or extending the femur nail once again.
It does kinda suck to go from essentially average to essentially average imo
Edit: as a side note, if you are doing LL, expect to be out of daily life for a year. Do not try to get to back to work asap and cheap out on recovery. Do not reduce your goal by not filling committing to stretching and PT. Not referring to OP, but If you have to say you "tried" to stretch daily, then clearly you are not doing enough. MyEvolution said that the majority of patients are lazy and succumb to human tendencies to slack off and not PT or stretch daily.
LL should be a full time job, you must push yourself to stretch many many times a day.
OP, I went through your post history and you stated that you could never touch your toes and was at least 6 inches away from doing so. I have no doubt this lack of flexibility caused you to stop early and really struggle through the process. For people who want to do LL, you must stretch. Alot.
