Would be interested in how close your method matches T/C's number.
It's pretty close. I used to call once in a while to get it as you suggest, but I'd rather not call unless there's something more important to talk about. My method always comes out a little bit less than the percentage suggests, but that may be due to compounding that I can't figure in. But I do accurately forecast how many dollars it will advance each day or week.
I like that a whole lot better than trying to figure out how long its going to take me to get back to square one on my equity funds, even though it's boring. I can't even remember when I made anything on equities; that is; for the last 8 years. Only TREA worked for me since Spring of 2000.
