You are misunderstanding me, again. Or answering a different question to the one I asked.
I understand fully the concept of Expected Value and Variance. I understand the Law of Large Numbers that straightens this out over time.
(Incidentally I have made almost 4,500 bets, not 300, but that’s besides the point)
The figures I have highlighted are Cumulative Profit, not Expected Value.
My cumulative profit told me that I had made £1200 last month, but when I tallied the amount in my respective bookmaker accounts it was just over £650 in profit. This was the second month in a row there was a significant disparity. I mentioned the big gap the month before with Hannah.
Unless I have seriously misunderstood the basics here, that has nothing to do with EV (it’s figure is at the top of the bet-log page, not where I am highlighting here) or variance.
My query/topic wasn’t a criticism of the product, which I have been very happy with (and Hannah’s customer service has been great), it was an attempt to see if anyone else had experienced this to see if I could get advice to limit it in the future.
I have taken more care with my placements this month, in case that was the issue. In future, I am only taking the cumulative profit as a guide, because I just end up getting annoyed at the end off the month if my figures don’t tally. So long as it’s in the right ball-park at the end of the year after another 10,000odd bets then I will be happy enough.
