Dalray,
I have very few bad ones, if I do as you must have read in some of my other posts I stop at 3 points down which I usually recover in 2 days which still gives me 3 winning days in the week.
The exception to this was last month where I had a shocking two weeks,
I don't know the reason except that I thought I might be tired of looking at this screen switching sites every couple of seconds and might have become a bit scrambled in the old brain department ( which turns 60 this month ).
I had a few days break and since then I have gone OK.
I don't know whether that was psychological on my part or whether my method fell into a rotten hole, in this game one will never know.

Cheers
