No, CT gives ~1 skill/year, as does MT and T4.
Sorry Andrew, but you are quite wrong on that, at least as far as Bk1..
Bk1 you get 1 per term, plus one for commission, and one for officer promotion. An additional is gained for 1st term. Automatic skills can add up to 2 levels (Best is Army and Army Lt) within one term, and IIRC 3 levels total.
Bk4-7 gives no base per term, plus a chance of one per year (usually aboug 40% chance on about 60% of years, or about 24% chance of skill per year, thus averaging 1 per term), plus one for promotion. Schools can grant 0-5 skills...
Bk1 ranges 1-6 skills per term, averaging 1.6 skills per term, with a sustainable rate of 1-3 skills per term
MT adds special duty, and bonus skills making the range 1-10 skills per term for basic. It averaged about 2.5 skill receipts per term, with a sustainable rate of 1-5 reciepts per term.
T4 was one per year base, plus 1 for special duty, comission, promotion (each of which was once per term) for a range of 4-7 skills per term, averaging about 5. Rankless careers, with a base of 6 per term, got an average of about 6.5... due to special duty.
I did the math when T4 came out, and Marc hasn't publicly swerved from those rates. Check the TML archives (ISTR it was either
aramis@asylumbbs.com or
ANWFH@uaa.alaska.edu that I posted it from.)
