Groundhogs Day

I've seen it probably 20 times, it's on right now.

I looked it up on wiki, Harold Ramis had said he was repeating the day for 10yrs on the dvd commentary. But later on in an interview he said it's probably more like 30 or 40yrs due to the fact he masters french, the piano, ice sculpting etc.

I'd always assumed he was locked in for 2 yrs or so. 

What'd you guys think?

Has to be at least 5 years, and I think that's being generous.
