Your 'lifetime' stats only show 138 putts, but you're already doing pretty good by averaging just under 2 putts per hole.
Par is established to include 2 putts per hole.
As mentioned above distance control is very important so if a second putt is needed it's a short putt. You want to avoid 3-putting.
Each putt needs to be hit so it will go past the hole (about 2 feet) if you miss, because there is no way a putt left short of the hole can go in. By the same token, any breaking putt you miss under the hole never has a chance to go in the hole either.
WGT sells a putting stroke strength measuring aid called Putter Pal. You can get the 10 hits for 10 credits version and copy the Putter Pal scale to a piece of paper you then stick to your screen under the stroke meter.
Outside WGT there are a couple of similar aids available. I use and recommend VGG Caddy. There is a free version of VGG Caddy, and a $3 minimum 'donation' Pro version that has more features.
Learning to 'read' the break of a putt is about experience. The more you play, the better you will get at reading the greens.
My lifetime stats show that to date I have made just under 30,000 putts (29,965) playing WGT over 28 months.
