This is the idea:
Bet one EC.
Here, I will test black and reds.
Wait for 3 results eg. RRB
Bet that these 3 results won't repeat in that order. So we bet BBR
Progression 1,1,2
So if we win on the 1st spin, we are +1
If we win on the 2nd or 3rd spin we are level.
If we lose we are -4 and wait for a fresh 3 spins.
Next progression line will be 2,2,4
Then 4,4,8
This is a safe and mild progression but one which from
my testing has solid results between the +5 to +10 range
from a 100 spin session.
