Awesome!! That’s they information I trying to figure out. Thank you everyone!
To be picky, though... your 16 percent and your rolling dice comparison is slightly off... 1/6 is actually a 16.66666(repeating) percent, which is what we used for our calculations. If it is really exactly 16.0 percent, and not 16.666666 percent, then your expected final contact number becomes (0.84^6)*1000... or closer to 648.7 contacts. I don’t know if those last 17 live contacts are important or not, but it is the difference between 1/6 and 16 percent.
