This is an experiement so far,
Procedure: Use RX, (or any other tracking method), to track the LINES; in RX "Line Statistics". Now wait until one line sleep for minimum of 3 cycles (18 spins) THEN wait for this line to wake up (to Hit). When the sleeping line wakes up (when it hits) BET the 5 unhit numbers within that particular Line.
Progression: 1 1 1 1 1 1 1 2 2 2 3 3 4 4 5 6 7 8 9 STOP
(A total loss of the progressionline will be about 310u, and shouldn't be impossible to recover from).
BR Needed: A minimum of 350u
First test was played with 1u bets.
Test 2. It could survive and recover from 4 losses.
