Does this make any sense to you?

A certain manufacturer of radio station automation systems uses the following scheme to record the lengths (i.e. durations) of audio cuts:

29 51 ce a0 c8 45 e8 3e = 1 second

29 51 ce a0 c8 45 f8 3e = 2 seconds

74 e5 01 c9 3a 57 fe 3e = 2.5 seconds

df bc 9a 78 56 34 02 3f = 3 seconds

f2 a1 a7 02 b3 b8 03 3f = 3.25 seconds

29 51 ce a0 c8 45 08 3f = 4 seconds

74 e5 01 c9 3a 57 0e 3f = 5 seconds

df bc 9a 78 56 34 12 3f = 6 seconds

29 51 ce a0 c8 45 18 3f = 8 seconds

29 51 ce a0 c8 45 28 3f = 16 seconds

29 51 ce a0 c8 45 38 3f = 32 seconds

29 51 ce a0 c8 45 48 3f = 64 seconds

29 51 ce a0 c8 45 58 3f = 128 seconds

29 51 ce a0 c8 45 68 3f = 256 seconds

29 51 ce a0 c8 45 78 3f = 512 seconds

It obviously has an exponential component, but there seems to be more to it than that.

I can't figure out why anyone in his right mind would record durations this way; most people just use an integer representing the number of milliseconds.
