Ok so marking it on the lens is the best plan.
Setting it up will be finicky because a small amount of turn of the focus ring at infinity makes a large effect but I will get it done.

The MFD measures from the sensor to the closest possible subject, NOT from the front of the lens (that is usually called working distance). So if you take 8cm+lens length+register distance, you will notice the MFD is not actually far off
Ah I see. I never really thought about that and I did assume the measurement to be to the objective lens.
