Pipes need enough down time to be at their best when you smoke them -- dry, rested and refreshed.
The harder you push them, the more their interiors never get a chance to completely dry back out, the more they lose the ability to deliver the flavor of the tobacco in them and the more they start getting sour and nasty on you.
If you end up with a wet heel, it can be a good idea to dig the dottle out, fill the last quarter or so of the bowl and smoke that to dry it out before resting it, but this only shortens what the recovery time would have been otherwise.
I experimented with this a while ago and found that even once every other day was unsustainable over time. The deterioration was slower, but cumulative and inevitable.
Two or even three times in a row is do-able as a short term proposition (although the last bowl won't taste anywhere near as good as the first did), but pipes need time to rest and recover after exertion, the same as you do. Football players don't have contact practice in pads every day, and weight-lifters don't work the same muscle groups day in and day out.
Same with pipes.
Note : written with reference to Virginia flakes. Burley seems to be a different story -- it seems to generate less of that yummy good heavy tarry funky gunky residue.
FWIW
