I know this is late.
I have done many plumbing projects.
I have used 5 wraps to T-Tape plus pipe dope. Also I forget the brand some t-tape is a little thicker than others. Thats why I go ahead and use 5 wraps to ensure I have enough.
I have had 0 leaks as a result.
Also make sure its not a slow acting pipe dope. This one is the one I use and has worked great. Its a prefence.
