What kind of VPD does everyone run during flower?

Currently beginning week 4 flower, and just wondering what everyone keeps their vpd range at. Currently running about 1.5-1.7 Is this too high?

I wouldn't worry about Vapor Pressure Deficit unless you are a commercial grower. I've been growing for 15 years and never once checked my VPD.
