Is Bowl Size Inversely Proportional to Burning Time?

[grue]

I just smoked my MM Patriot cob for the first time, and it was quite brilliant. I only relit twice and it burned nice and smoothly, although a bit hot but that's my fault.
I noticed, though, that it lasted a bit under an hour where my Mizzou, a considerably smaller bowl, lasts me an hour or more smoking the same tobacco, Planta California Dream.
Is the bigger bowl a factor for a faster burning or was it just by chance? The cob is brand new and had no cake at all, where the Mizzou has an almost two month cake built. Could this be it?

Just wondering... ::
Here it is before the satisfaction.

My Mizzou only lasts about 15mins, which is why I rarely smoke it. My Washington which is bigger usually lasts around 35mins.
In my experience a bigger bowl smokes longer.

Strange, I must be doing something wrong, or right!

I'm not sure, but I would guess you're right in thinking it probably has something to do with the cake?

I think it depends a lot on the tobacco and the cut. Flake, plug, and rope can last quite a while in a small pipe, whereas dry loose tobacco can burn quickly in even a large pipe with a narrow bowl. But the idea that small pipe equals short smoke is not accurate. It depends on other things too -- not least of which is how you smoke. I once took a Chesapeake (small Old Dominion cob) to a bluegrass festival concert and went outside during the intermission for a quick smoke. It wasn't so quick, and that got me thinking. I did make it back to my seat for the beginning of the rest of the show, just.

I'm with MSO on this one. Tobacco, cut, and moisture content need to be taken into consideration. Another big one is packing method. There are too many variable to capture, but lets just say, a loose pack results in less tobacco than a firm pack in the exact same bowl filling to the exact same level.
If I put a ribbon cut that is dry in a bowl it will go much faster than a dry fold and stuffed flake in the same bowl.

I might have packed it a tad looser than I usually do...
