It's just one of the little added novelties of the 200, you get all the real data plus some things it imagines. The other evening I looked at my rain rate graph and it was 34.59"/hr. That didn't seem to likely, so did surgery on the dbase.csv. I have a 100 sitting within an inch of the 200 and never has done that in 4 years.
When I first got the 200 I had immediate problems and so over a 2 month period I tried every imaginable way to cut the spurious readings with essentially no success. I finally went back to the 100 and the 200 is data logger only.
I have on rare occasions had a single bucket tip due to wind. If it was within a drop or two of tipping, then stopped raining, but later wind or some physical vibration caused it to finally tip, so the reading total is correct, only the timing, but you only get .04" per tip, so that's not your problem, it's just an unfortunate characteristic from the factory. About the only fix I've seen is to spend $500-700 on a Davis and still have to deal with USB data logger problems.
