Should I be concerned?[/QUOTE

No if it's not the rent money your using as capital to punt with, yes if this bird flu pandemic goes human to human [I'm stocking up the food supplies and candles :-).]

What I find interesting in your figures is the loss/skinny profit periods. It certainly reflects my bad periods and good periods to a large degree.
OK we have Jan. And Feb. Hot as hell and lots of 2 yr. olds running around as 3yr. old with ************ all form. Difficult period. March, well those 3 yr. olds have some form now and there is good prize money around [less dodgy races and trainers doing their thing]. More money around basically and more reliable form.

Winter, the flip side of summer with very little money around and then an upswing into the money period of spring. Xmas period into Jan. early Feb. is probably a good time to do something other than punting. I certainly wind down my punting $ outlay during that time. A tough period.

I find all that timing reflects my system and/or handicapping efforts similarly and that in itself is interesting. Well maybe it is if many other punters have a similar experience with different times of the year.
