I have been using Perifit for a couple weeks but I am very confused about its strength measurements and how to use it correctly,

The instructions say it should be almost fully inserted - I am starting like that but tend to squeeze out almost half or more of it when I. Exercise and it keeps happening .

Not sure what to do - when I put it back it often stops and tells me me not to touch it during exercise etc but sometimes I am almost completely squeeze it out 😂

Also strength measurements are very different when I don’t readjust it when it gets half way out - I am getting strength about 300 grams vs 1700 otherwise! On the other hand, when I manually keep it inserted I am sometimes have problems with relaxing fully, but gently pressing it in and preventing it from sliding out seems to work best.

But I am very confused by wide variety of strength measurements and instructions don’t mentioning this problem at all - am I the only one?
