Talk alone and you are heard

Everyone shares one channel. Talk together and nobody is heard. Change the crowd and how often each station talks, and watch the successes move.

Solid curve: slotted ALOHA S = G e^-G, peak 1/e = 0.368. Dashed curve: pure ALOHA S = G e^-2G, peak 1/(2e) = 0.184. The yellow dot is your live measurement. Push G past 1 and watch it slide down the right side: more talking, less heard.
