Silistretcher question

[Cleareyes]

i recently rediscovered my silistretcher after putting it away for many years. I wanted to confirm a few things I was unsure about.

Am i still getting a stretch / making gains by wearing the silistretcher alone without using the belt to stretch in different directions (so simply putting it on, turning the piston and then laying down watching TV) or do i need to include the belt to actually make it work?

If i use hanging weights do i also need to remain standing or sitting forward at all time to make the weight hanging actually work, if so how long would be good to hang with some weight each day i hang?

Thanks!
