Step 1: Run was worth points, so it was valid, can be ignored
Step 2: All runs are valid, can be ignored
Step 4: Does not apply here, can be ignored
Step 7: Is not an IL, does not apply
Step 8: Run was worth points, so it was in your top 60, can be ignored

Step 3: ceil(5*0.005) = 1 So let's only remove the last run (Darko's)
--------------------------------------
That leaves the meat of the algorithm:
Step 5: (all time values are in seconds)

The mean is 156.355s
Your run is 152.230s
5.1: Your run's signed deviation from the mean: 156.355 - 152.230 = 4.125s

Last counted run (8BitisGr8): 159.120s
Lowest (unsigned) deviation: 159.120 - 156.355 = 2.765s
5.2: Adjusted deviation: 4.125 + 2.765 = 6.89s

5.3: normalized deviation: 6.89 / 2.765 ~= 2.49186256781

certainty adjustment: 1 - 1 / (4 - 1) = 0.666...
("e^" means Natural Log)
5.4: e^(2.49186256781 * 0.666) -1 ~= 4.25710486939
--------------------------------------
Now we give a bit of a bonus if the run is extra extra long
Step 6:
length bonus: 1 + (152.230 / 43200) ~= 1.00352384259
Your points: 4.25710486939 * 1.00352384259 * 10 ~= 42.7210623684
