I brute forced the encounter counter behavior. It's essentially exactly what I had speculated in the past, but I had not verified it previously.

I think whether or not you get into the battle has to do with an internal formula checking if the game can lay down the battle grid or not. I've never understood exactly how this works, but it's well-known that sometimes you won't get into an encounter up against certain walls.

50 step units is about 0.83 seconds or about 5 Brian steps. Brian's speed is 2 step units per 1/30th of a second (one frame).

Exactly every 50 step units it rolls for EncounterChance = (Step Units / 2000)

50 step units = 0.025 = 2.5%
100 step units = 0.05
150 step units = 0.075
200 step units = 0.1
250 step units = 0.125
300 step units = 0.15
350 step units = 0.175
400 step units = 0.2
450 step units = 0.225
500 step units = 0.25
550 step units = 0.275
600 step units = 0.3
650 step units = 0.325
700 step units = 0.35
750 step units = 0.375
800 step units = 0.4
850 step units = 0.425
900 step units = 0.45
950 step units = 0.475
1000 step units = 0.5
1050 step units = 0.525
1100 step units = 0.55
1150 step units = 0.575
1200 step units = 0.6
1250 step units = 0.625
1300 step units = 0.65
1350 step units = 0.675
1400 step units = 0.7
1450 step units = 0.725
1500 step units = 0.75
1550 step units = 0.775
1600 step units = 0.8
1650 step units = 0.825
1700 step units = 0.85
1750 step units = 0.875
1800 step units = 0.9
1850 step units = 0.925
1900 step units = 0.95
1950 step units = 0.975
2000 step units = 1.0

Cumulative math:
P(A or B ) = P(A) + P(B ) – P(A)P(B )

0.025 + 0.05 - 0.025 x 0.05 = 0.07375
0.07375 + 0.075 - 0.07375 x 0.075 = 0.1432

Since the counter resets, it's harder to exactly calculate the chance of two encounters over a set distance. The following covers chance of at least 1 encounter.

Cumulative:
50 step units = 0.025
100 step units = 0.07375
150 step units = 0.1432
200 step units = 0.2289
250 step units = 0.3253
300 step units = 0.4265
350 step units = 0.5269 ~50%
400 step units = 0.6215
450 step units = 0.7067
500 step units = 0.7800
550 step units = 0.8405
600 step units = 0.8883
650 step units = 0.9246
700 step units = 0.9510 ~95%
750 step units = 0.9694
800 step units = 0.9816
850 step units = 0.9894
900 step units = 0.9941
950 step units = 0.9969
1000 step units = 0.9985
