Class 2 WTF?!! It's class 4 on a good day... Who gave it that rating?... Now I see it's changed WTFx2?!!
I've gone through all the history I have from emails (and a table that stored this info for the last 2 years) to put together the history of ratings and where they came from:
This is viewed by clicking on the "discussion" link adjacent to the class rating:
There are about 2,000 ratings I haven't identified sources for yet, many from guidebooks, but I have identified over 6,000 ratings.
As a heads up, class ratings, the rater, and their comments are now viewable for every rating provided. Any time someone posts a comment or alternate rating, It notifies me and all other raters of the peak in question so that we can be alerted to the comment and respond/revise if necessary.
