not expecting the expectedUNQ chains

i'm using this formula from sc00bz cheat sheet
expectedUniqueChains ~ chainCount / (tableWorkFactor / 2 + 1)
chain length: 150 000
my current chain count: 50 000 000
after perfecting: 7 080 082
merges: 42 911 282, 85.84%
odd the numbers don't seem to add up since 50 000 000 - 42 911 282 <> 7 080 082
anyhow we'll skip that part
keyspace: 7.35092E+11
table Work Factor: 10.2
expected Unique Chains: 8 194 836.455
seems like i'm roughly 1 million chains short, is this due to the new reduction function? am i just doing it wrong? is there some new formula to use?
