I really should have replied before now, but I didn't, so my apologies. I think a puff counter is actually a little useless (to me), too. However, I can see how it might be useful in some situations that don't apply to me, and I thought at least one person was out of line on this thread, too. If you want a puff counter for whatever reason, then get one. Depends on for what reason. If you want one for a valid use, then go for it. If you want one for the heck of it, then you can probably ignore it as a reason to get a certain PV.
Again, my apologies for not throwing in my two cents. Ignore the sarcastic replies of others.
