I'm not understanding what you are saying here.
The Gibbs thread is a 8x1mm, so a full turn lowers the bottom plate 1mm. If its a finer thread the same full turn doesn't drop the bottom plate by the same amount - 1mm. (Or that's the way I understand things to work)

Made in China they will most likely be metric and if I was going to guess they are 8x0.9mm which is the same as the Yaqi.
The adjuster knob should have threads on both sides of the knob. The threads on the side that are screwed into the razor head are the ones that are responsible for the actual adjustment of the blade gap. It is a case of accuracy and precision. The way it is defined think of a target, where is the bullseye then can you hit it. If you can that means you are accurate. Precision is if you fire a bunch shots how tightly can group them on the bullseye.
Gibbs razors were never precise from one razor to the next if you set them strictly by a dial number but they are accurate because they use the same pitch for the thread from razor to razor. If they bottomed out the dials on the thread first for each razor then put the numbers on the dial they still won't be precise since if you switch the dials to different razors the numbers would be off again. The only way to get a precise translation to compare Gibbs razors is you need to bottom 2 of them out on the adjuster dial then make note of how many revolutions and on what number they land on when both are gapped the same. Then and only then can you adjust them from that point 1 number or amount of turn at the same time where they will be accurate and precise regardless of what the dial number says.
Short story long if that thread is not the same on the heritage it is neither accurate or precise and a major fail if you are selling it to shave like a Gibbs and not worth buying. Unless I am misreading the market and buyer, the real customer and the one that is going to sustain the sales is the one that wants a Gibbs razor that they don't have to modify blades for not something like looks like a Gibbs but doesn't shave like one. This isn't a Janus adjustable that you can get away with it not shaving like a Toggle since the selling point is it is a copy of design not the function of the shave itself.
It is a simple fix which is have the threads match an original Gibbs.
