Any just extender girth gains, with long term use?

I know this has been discussed in the past, but I wanted more recent data on this. I know extenders are for length, however, I’m told the glans can grow as well as very moderate girth increases with long term use. Most of this may be to just improved EQ, but in almost all cases people supplement with some jelqing. If you were to do 100 hours/month in an extender over a year, with a goal of gaining an inch in length, is it reasonable that you would gain .1 to .2 in girth, without any girth exercises? I would still be warming up, doing the odd manual stretch, etc. Cheers.

When I first started, I didn’t do any manual PE exercises and I gained 0.15 in girth. Since then I haven’t gained girth from the extender so I would assume it’s from increased EQ.
