Unusual Series of Retrains on ADSL

Is it possible to ask somebody to generate a Visual RADIUS print for my line? My ADSL has been pretty stable lately (last train I looked at had been connected around 75 days or so), but today I looked at my router stats and it says 38 retrains - which means 37 in the last week or so?
This seems a little excessive given the previous period!
I notice that at least some of the time it has trained around 1Mbps higher downstream than the previously stable speed, doesn't the Exchange equipment keep any kind of history about what a line can achieve?
For the record the stable speed was 6895 kbps downstream / 1075 kbps upstream. Currently it seems to have really got itself into some problems at 6327 kbps down / 415 kbps up.
Nothing has changed as far as I can see, certainly nothing in the house and nobody suspiciously tinkering with the cabinet that I've seen (chance would be a fine thing, no sign of a FTTC upgrade here ).
Just really wanted to sanity check and make sure I'm not imagining things! Thanks.
Update: Generated some graphs from my router stats. The retrains went through the roof today, and the SNR is all over the place.

I've already lost more than half of my upstream speed!

How are your speeds at the minute?

Tuesday night and Wednesday morning were very wet here, several extremely heavy downpours in quick succession so it looks like something got flooded between me and the exchange.
I'll give it a few days to make sure it is stable and then try resetting it.
Thanks for confirming I wasn't imaging it!

Upstream SNR margin plummeted from 16 dB to less than 2dB in an hour and triggered another 5 retrains in quick succession.
No rain today either which doesn't match my previous theory .

Did anything in your house come on at that time?

I'll see if it does it tomorrow when I'm there in case anything presents itself outside.
