Years go I would chase flavor to the point of getting a mouth full of hot ash. That pretty much sucked so I came up with a system to check how low I was. I take the pick end of a tamper and push it into the bottom of the bowl. If I find nothing but loose ash, i dump it as I got tired of hot ash in my mouth. Use your picks guys so you can see where you are in the bowl. If I scrap the sides and get more tobacco, I can usually tell if there is more to be smoked. Most times there isn't but sometimes there is and the flavors down there are worth the effort and risk of hot coals in my mouth.
I have it down to the point where maybe once a month or 2 I might get ash in my mouth. If it didn't taste good I wouldn't bother but down at the bottom can be some really great flavors.
