I daily do my excercise with tactics trainer. There are always a lot of comments about the rating. Its too high, too low, whatever. Also I've seen comments like '1400', '1624', '2001', '1873' etc. etc. Wouldn't it be an idea to ad to the rating a highest and lowest it ever reached? I know the rating is subject to the players and I am guessing every tactic starts at 1200. Tough ones climbing rapidly and easier ones climbing slower or dropping. I'm also guessing after some 100 attempts or so the tactic reaches its approximate value and will rise and fall less in time. This is where the highest and lowest should start counting. This way we can get a clearer view of a problems true rating.

In my experiance tactic-ratings drop or rise just as much as my own rating rises or drops after completing the tactic. Since I am not the only one playing, the rating of the tactic should have a lower deviation, thus also a truer value could be accomplished.
