The more you play with it, the more the free travel will be permanent.
Also, note that glass implants rarely stay where you deposit them if they’re not coated: usually they take a hike to whatever lowest point between muscles and bone they feel like settling in. Mine moved a good 10 mm backward in my left hand and they settled so deep next to the thenar muscle - almost behind it - that they’re almost invisible. They work fine though, and they’re not going nowhere anymore.
That’s kind of an unfortunate consequence of the lack of conformal coating on DT implants if you really care about where you want them exactly.
