Rich, draw your own conclusions. SeventyThree(s).

From the FT4_protocol.pdf document at

Modulation uses 4-tone frequency-shift keying at approximately 23.4 baud, with tones separated by the baud rate

From the Brief Description of the FT8 Protocol at

The mode name "FT8" stands for "Franke and Taylor, 8-FSK modulation".

FT4 is different than FT8, JT65 etc. thus the designation is different.
I’m no guru, but where FT8 switches frequencies, FT 4 sweeps from frequency to frequency. Someone else can describe it better than I, I’m sure. But they are different.
