The following table shows tape counter numbers for various times
for both T-120 and T-160 VHS tapes.  These numbers were derived 
by recording a digital clock on to both a T-120 and a T-160 tape
at the EP speed and observing the counter at fifteen minute
intervals on playback.  The machine used was a Sharp VC-A610; 
however, the numbers also apply to a Zenith VRD 100 and an RCA
VMT390.  The counters may be different in other of VCRs, 
particularly older models.
