Can anyone explain why transmitters have fewer channels in PPM then they do in PCM?

I thought this was an annomoly with my 9C but I see that is not the case.
The following is my WAG on this. The transmitter has to get ALL of the data out to the RX within a certain amout of time (frame) before the next frame starts with the next round of new data. PCM simply takes more of that time per channel to be encoded than PPM does. It simply runs out of time.
