Can someone take a look at my tree strap stitch?

I've read quite a bit on this and some testing has shown this stitching pattern to be stronger than bar tacs.
It's how I do them now.

+1 to this. Straight stitches seem to be stronger from what I have heard....We had a member/vendor here actually run some tests in the past to confirm this. Bar tacks are ok but the long straight W pattern seemed to win out.

Mad PC Paint skills right?

I just finished these tree straps for a hammock project I'm working on. I fold the end over 6" and run a bar tack every inch , with a straight stitch diagonally between each, leaving a two inch loop at the end. The first tree straps I bought a few years ago were from Paul at AHE. That's how he did them and I've been doing it ever since, with no issues.

I read a long document on various ways of connecting various materials (rope, webbing, chains, chains-rope, etc)

It had a section on webbing, which may have been one of the original uses for the chart showing the WW method as being strongest.

IIRC, that design is only the best if it is to join two separate webbing ends, to be used to extend the total length. (All the force is a shear force along the length of the webbing)
For situations where making an end loop, it was not recommended. I think it suggested using Bar Tacks.

I really can't remember if I saw the document here, or another place. It had a lot of focus on sailing.

I need to go back and find the article that was from. The problem is that the illustration was taken out of context. The W stitch was found to be strongest when only sewing SLINGS. In fact for our purposes the mountain climbers three(oops six) bar tacks was found to be the strongest when sewing load bearing loops into a piece of webbing.

Edit: found it. It's about 3/4's of the way down in the article. The conclusion was actually 6 bar tacks was strongest. Even close packed straight stitches was a good close. The often cited diagram showing W stitches as strongest is actually labeled for slings in the next section. All of this said we shouldn't be in danger of shock loading at the extremes for any of this, so it probably doesn't matter too much.

Gary at Readystrap is in the business of making straps---nothing but straps (best choice for tree straps out there IMO). He's done a lot of testing on stitching as a result of customers giving him specifications for performance. In post #7 he has a nice chart:
