The segment between 1974 and 2000 is very challenging for a newbie. There is no clear wave pattern, so I make some measurement. Wave 1949-V)I1]-1952 moves up 83.70%. Wave 1952-V)I3]-1953 retraces 13.79%. Wave 1953-V)I3]-1961 moves up 191.43%. Wave 1949-V)I-1961 moves up 623.28%. Wave 1961-V)II-1974 retraces 43.06%. Wave 1974-1976 moves up 80.02% is nearly equal to Wave V)I1], so it may be V)III1]. Wave 1982-1987 moves up 256.71% is in the same order of magnitude of Wave V)I3] which moves up 191.43%, so it may be Wave V)III3]. Wave 1990-2000 moves up 407.97% is in the same order of magnitude as Wave V)III3], so it may be Wave V)III5]. There is a small segment 1987-1990 which is very difficult to count, can it be a Wave V)III4] running correction?
