In 2252 spins if you play two numbers you need to touch 121.7 times.
This is the probability 2/37.

I hit 124 times in 2252 spins.
The probability is 121.7.

OK
24
         1         play  24-1
29                play 29-1
22                play 22- 29
       27                 22-27 .................so on

I tested 1933 spins attacking the last two numbers  systematically.
Permanence Wiesbaden.
According to the probabilities I will touch 104.5 times.
I hit 104 times .. This is a small sample but what stability!
I feel that to always play the last two numbers gives a little more (dealer a little robotic)

Interesting. Have you tried taking the last two numbers systematically on real permanence ?
