Increase sweet spot and reduce res drop off

I have modded my G2 to get my eyes as close as I can to lenses, My IPD is 65.5ish. I used to focus on ensuring the headset was set to my IPD but after reading the post from thelonesomeguy, I messed with the IPD and eventually ended up setting it to its widest setting, Now the headsets sweet spot feels larger and more importantly the resolution drop off from sweetspot to the periphery feels less aggressive and more gradual.
