Boost leak testing

So i just searched on here for almost an hour and found nothing. I was looking at at a thread and saw that a few guys were saying that upon doing a boost leak check a slow boost drop is normal. Is this? they said that if you put 30 psi in it, its normal to lose pressure in 60 seconds or so. When I have done my boost leak tests mine does this. I put about 30 psi and it slowly drops to 0 and id say it takes about a minute to two minutes. I have sprayed down everything and found no leaks. and boost to where i am supposed.
It would make me feel alot better to know this is normal. So basically you wont hold 30psi for good. It will drop out slowly from what I understand. Is this correct

Thank you.

If you are putting 30# through the system and you can't physically hear the leak, i'm sure that you are fine.

You should be just fine with this it will taper down and eventually loose pressure
