OK, have had an interesting couple of days. Stats are on MDSW user Gedpie, there is a gap that I'll explain.
Looking at Tuesday's stats there is a jump in SNRM to over 7dB, which was unusual. When I got home I discovered my media PC in the garage had powered down about 10 minutes before the SNRM jump, I switched it back on & saw that the PSU fan was seized. You'll then see a gap in the stats, as said PSU decided to expire very loudly tripping all the sockets in the house as it did so.
Now the media PC had an important job at 8PM (recording GBBO) so a PSU was culled from another PC, which resulted in the SNRM going back to 6ish & then plummeting to under 2. Drastic action was needed so the PSU was pulled from the PC doing the MDWS stats, hence the gap in data whilst I sourced a new PSU, which went in yesterday & stats resumed.
So it looks like the dying PSU was causing interference, but I didn't get that increased SNRM when the dead PSU was out of the equation. I think I'll tinker at the weekend unplugging stuff in the house & checking the effects.
My latest stats are below, FEC did go off the scale after the PSU fun, up in the 1,000,000 scale, but things seem to have settled now, ES look almost none existent, attainable is over 38000, still banded at just under 30000 though.
