Angry Are even count sprockets REALLY a problem?

So my Vee came to me with new 17/42 sprockets and chain on it.I put on a 16 tooth front sprocket,and now I am reading that this could cause problems? (16/42) Doesnt make any sense to me.Is this an old wives tale or what?
thanks!
Steve

The theory is the same teeth hit the same subset links on the chain all the time so the wear pattern will be set instead of random. In reality, there doesn't seem to be a noticeable difference.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

I never thought about this, but I am always up for a mathematical challenge. How many links does a V-Strom chain include? If the number if links divided by the number of teeth is an integer, then each link will hit only one tooth. If the number of links divided by the number of teeth is an integer plus 1/2, then each link will hit only two teeth alternately, and this would be possible only with an even number of links and an even number of teeth. I could continue with other possibilities, but it seems to me that if each link hits more then two teeth, then the chain should wear acceptably. OK, experts, where am I going wrong?

Then a 16-tooth sprocket will mesh each link with only one tooth, because 112 / 16 = 7, an integer. Whether or not this will cause premature wear to a practical degree of concern, I can't say.

My head hurts!

Is it because of the maths or the red wine?
