First, to better understand the issue. This is when record keeping is a good idea. Minimum Columns to include are session length, $ session win, $ percentage loss. Filter the data to determine average $ win and average $ loss.

What you’re describing is an average $ win which is far less than the inverse of your average $ loss. Now, if you're a typical card counter, you will win an average of 60% of sessions played. Multiply $win by % win - measure against average $loss by % lost - hopefully there is a plus sign at the end of the day. Regardless if $ won or lost, start fooling around with the numbers. What happens if you can reduce dollars lost per losing session to begin with and the reduce that $lost to the actual inverse of dollars won. What happens if you can increase %sessions won. What is the impact to overall profitability. Clearly, the impact is significant.

Now for your actual question (pretend you’re Vondox) - $2500 loss is within parameters at a min $25 table - but so is $2500 win. Last month, I had 3 losses (lot for me) totallng about 2k or 2.1k. One of them was specifically to let the casino book a win. Also had 3 2k wins and 1 or 2 $400-$500 wins. This month, no losses yet on 4 sessions totalling about 4.3k on 4 sessions with local tight spreads. Maybe 10 hours played.

In my view, optimal spreads are highly predictable card counter giveaways. They are knock it out of the park strategies. Experience and seasoning will disclose to you other strategies which would appear to make you look amateurish but in reality ncrease your EV. Illleabe it there.
