Locked Is the bandwidth for #FST4 quoted correctly in the v2.3.1 User Guide? #FST4

I am translating the v2.3.1 User Guide. In section 17.2.10, Table 7 quotes the FST4-15 Keying rate (Baud) to 16.67 baud, whilst the Bandwidth is quoted as 67.6 Hz. Should that be (16.67 x 4 =) 66.7 Hz, coresponding to the Keying rate/Bandwidth ratio of 4 or a very little less in the other 4-tone modes?
