So if you look at WCP's page on the GT2 belts and pulleys they sell, they refer to it as "GT2 compatible profile." I assume that this is just a legal workaround to use the GT profile.
And yes, I believe that GT (3mm) belts can be used with HTD (3mm) pulleys, and if I recall correctly, it performs about as well as HTD with HTD.
Pretty much,the belts are not produced by Gates and the profile is not the same as the GT2 or GT3 profile by gates, it slightly different. Will be putting up test data over the next few months to compare the profile we sell vs Gates GT2/G3.

That's excellent, thank you! Any chance you can also throw in testing of HTD so that teams can compare your data against something most teams are more familiar with?

Will do. Let me know if there is anything specific you'd like in terms of testing.

As a side note the pulleys we sell and future pulleys we will be releasing are the actual GT profile. The pulleys are free game for anyone to sell/make just not the belts sadly.

Thanks!

That's great news! It'll be interesting if teams can use the more compact GT pulleys to make belt-in-tube drivetrains using the 2x1 VersaFrame.
