Help Calculating Mux Specs from MT-088


I've been putting together this small table for comparing mux specs for an ADC front end. I tried to use the formulas from Tutorial MT-088, but the numbers don't seem to add, specially settling time.

I'm considering Rload as an op amp input (10M). The charge injection number for ADG1409 with 1nF Cload is 50mV. Does it mean every time the mux switches on, the actual voltage is going to be off by 50mV or does this settle too?

If an expert could take a look at the table, that would be nice!
