Weber Equivalent with Fat Boy

I took a 3 year break from shaving, and am on shave #4. I've been using a Gillette Fat Boy on setting 3. I also have a new Weber PH inbound. So I know what to expect, what setting on the Fat Boy would be the rough equivalent on the Weber? Thanks

 

at a 5

 

Perfect! Exactly what I needed to know. Thanks.

 

I would also say setting #5 on a Fatboy, but as with everything, here, YMMV. I just found the setting to be closer to #7.
Good luck with the Weber and it is a very nice razor!

 

Thanks much. Appreciate the info.
