Sounds about there. Another half toke on the ash would have done it, but there is certainly no rush.
How long do you hold your hits for? This is often the deciding factor. People might tell you you get most everything in a few seconds,but IME this is simply not true. Even after 60 seconds SWIM still exhales valuable alks. For this reason he often flies with a
balloon.
Be well and good luck.

"Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it." ~ Buddha
