Why isn't tactics trainer rating Glicko rated?

I'm on a free membership meaning I can only do five problems a day. And for each problem I solve, I get 8-10 points. Everyone starts off at 1200, so it takes strong players a ton of time to get problems that match their strength. So, why not make tactic ratings follow the Glicko rating system like live chess where it jumps up quickly for the first few problems and then stabilizes as you do more problems? It's been about 9 days now and I still stuck solving problems rated 1500 when in reality I should be getting problems rated 2300-2600.

How do you know you should be doing 2300-2600 problems? Were you a member here previously?

If you are a titled player, why not just write in and get a free membership?

I've solved tactics on other sites. I'm 2300 on ChessTempo. I'm not titled, yet.

I agree with your proposal, for players. The tactics positions themselves have their ratings adjusted as if they were players, so maybe the ratings of the tactics positions should change more sedately.

Still, it's not THAT hard to become a National Master.
