The first 5 competitions had a total of 77 problems, the next 17 had 14 each, and the last 41 (thru 2002) had 12 each, for a total of 819.
I have now got up all the problems, and solutions for all years except some of 1941, 1942, 1948 and 1949 (41/B7(2), 42/A6, 42/B3, 48/A6(1), 48/B2, 48/B4, 48/B6(1), 49/A1, 49/A2, 49/A4, 49/B6).
