If it's cheaper than everyone else, there's probably a reason for it! Second guessing spring wind (wrap) is something no one should have to do!
The worst part is that after a small investment of time on the front end to fixture it will take no more time to do it right than to do it with error.

This is the error that occured (mirroring the image) as I talked to Jeff myself and has corrected the hole pattern problem. Jeff at Black Diamond Xtreme has been very helpful.
To help in this situation, the helix is a good helix and works well when setup correctly. To correctly setup or match what the wrap percentage would be....
1) Take apart your secondary and grab your stock helix and pink spring.
2) act like your going to install your spring/helix at your desired wrap in this case would be 3-3
3) Take the sloppyness out of the spring like you were just going to twist it clockwise (BUT DON"T START TWISTING) Use the same amount of pressure between both stock and aftermarket helix;s
4) Take a black magic marker and mark where the tip of the ramp is and the nearest mounting hole on the helix would be.
5) Grab your helix (and it can be any aftermarket helix) and use all the holes to find the closest that matches up. Mine ended up being 1 in the secondary and 3 in the helix. Now I am at 0 and 3
6) Install your helix.
It all goes by twist pressure and feel mostly.
So if i am understanding this correctly you were initially set at 1/3
Now you are running 0/3 with the bdx helix.
Have not installed it yet and looking for a starting point.

Start with a properly indexed helix is my best advice

Yes, mine was the 1st batch that I was able to get from BDXtreme. I now have a corrected one from Jeff and it is right on the money now

Is it right on the money exact now or are the holes off just a bit like mine?

Checked right on now, got my new helix just before the TY Giveaway ride. Put my stock helix to it, matches right up with a pin in each hole
