A long time poster says if you must play double dozens play 1 and 3
testing with gr8 progression with a tweak
1 1 1 1 1
3 3 3 3 3
5 5 5 5 5
bet 1 unit 5 times, if even or up stay at that level
if down more than 1 unit move up to level 2 of 3 units per dozen
after 5 spins assess if up or down
if down more than 1 move up the next level to 5 units
if at any level u get back to even or a new high go back to level 1
good tests so far
eh its nothing special
maybe some tweaks
