Heh, bitch I'll remember that if you ever have the pleasure of working on a cabinet freshly decorated by someone's dog with it hammering with rain and the wind whistling while I sit in my nice air conditioned office

ok now look at our network - if each house is a component, and they all switch on ur going to stress the PSU (tap in the pit, mux, yadda yadda, and all the way back to the headend). I know its a strenuous and simplistic comparison but it almost works lol. that kinda explains the RF drops.
upstreams - basically if a channel is clogged then our modems do try for a different channel but if there aren't enough unclogged channels what you gonna do? lol

1) Not really true, the customers don't need to have their devices on, the RF power will happily go down the drop cables whether the devices on the other end are switched on or not. The variations in signal over the course of time are due to ingress and environment not due to people plugging and unplugging things signals are split the same regardless. Unless of course you're suggesting that what people do on RF taps affects what other customers are seeing considering signal is split equally between them and terminated where there's nothing connected.
2) Not really true either, modems don't magically migrate to a less congested upstream, they'll take whatever the uBR offers them and only if the channel is congested to the point where they can't acknowledge the upstream and complete the process will they give up and take another upstream channel offer (suggest you read up on UCD advertisements in DOCSIS).
