I've been fairly consistent at working on tactics on CTS. In the last week, I've only dropped below 1400 once. Before, I would continually drop below 1400 and then gradually climb back up only to drop back below 1400 again. It was a roller coaster.
But this past week, I've stuck to it pretty religiously and I've been able to maintain some consistency. The last backslide I had pushed me to just above 1400. But I've recovered nicely and am now keeping it pretty steady around 1420-1430. I don't know how long I'll be able to keep my rating at this level.
I'm a pretty average tactician in the CTS community.
