Is the tv.cache file shrinking because of the season?

[Jeremy Nicoll - ml get_iplayer]

I'm using 2.90 still, having not updated yet (because I have to rework all
my own changes when I do and I don't feel like it today), so maybe this is
my own fault...

In my wrapper for g_ip, one of the things I check is the size of each
freshly populated cache.  While the radio.cache is fairly constant in size
(of course it does vary from day to day) at around 3300 lines at the moment,
the tv.cache I'm seeing has fallen from around 2100 lines maybe a week ago,
to just 1815 or so lines now.  There's been a steady decline, day on day.

I realise it could be a BBC-ism, perhaps because many regular programmes are
suspended while the seasonal dross replaces them... but maybe not - after
all for every programme removed, something else has been transmitted.  

Does anyone else keep an eye on the number of entries in these files?
