Is this shaft fitting corrects?

I recently did the shaft optimizer and got the pictured results.  They suggested a stiff shaft, but I was taught that if you are in between stiff and regular, you should go with regular.  Can anyone help? Also, I've been seriously thinking of going to a graphite shaft since I like the lighter feel of an iron with graphite.

How old are you and how athletic do you consider yourself. You have somewhat of a slow club speed but a fairly fast tempo. Also a high handicap. Do you think you are going to make some swing changes anytime soon or have you been slowing down?

This was with a 7-iron.  The assistant said I had a fast swing speed.

FYI - The average club head speed for an 8-iron is 87 mph on the PGA tour:

according to the chart above, with a 95 mph ss, you should be solidly in the X-stiff range, unless your tempo is a 2.  5 more mph and you'll be off the charts.

I have an extreme slow tempo. I am trying new shafts, and I probably need xstiff at least in my 7-PW. I get a lot of ballooning sky high approach shots. The distances are okay except when playing in the wind is becomes an issue.

I would go with the Project X 5.5 probably. You seem that you definitely shouldn't get a regular (~5 rating) shaft, but the KBS Stiff (a 6.1 rating) is probably too stiff. The Project X is a nice medium. I recently did their shaft fitting as well, and found through personal testing that with my tempo of 5 and SS of 88ish with a 6 (you're swinging a 7, which will actually be slightly slower). The KBS fits me perfect, with the 5.5 a tad bit soft and spinny for me, which makes me think it would be a good starting place when you test out clubs. But either way, go out and test the different shafts if you can before buying to see which gives you the tightest dispersion.
