Win streaks, no Mondays: betting system

Every filter so far selected matches; this template also excludes them. NOT groups are how you carve exceptions out of a system, and here the exception is the start of the week, low-profile fixtures, rotated squads and odd scheduling.

How the filter tree works

• Result streak: the home team arrives on a winning streak of at least 3 matches, any venue.
• A NOT group wrapping day of week: matches played on Monday or Tuesday are thrown out, whatever else is true.

The pattern to remember: AND combines requirements, NOT subtracts a slice you do not trust.

What to watch

• The exclusion is a hypothesis like any other. Maybe early-week fixtures are fine; only the comparison run can say.
• Removing days costs sample size, and streak filters are already selective. Watch the bet count.
• Beware of stacking exclusions until the system fits the past perfectly, that is overfitting by subtraction.

Tweaks to try

• Run the same system without the NOT group and diff the two curves; that difference is the entire value of the exclusion.
• Exclude congested midweeks instead, via a match-density filter.
• Raise the streak to 4 to sharpen the base signal.

Exclusions must earn their keep. Measure this one in backtesting on Pinnacle closing odds for soccer.
