time_shift ADC property doesn't work with two fast ADCs
With one fast ADC on a 524kHz IOP, time_shift of zero can result in cycle times 8 usec longer over time_shift of 8, but when two fast ADCs are running, time_shift seems to have no effect. The times are always similar to times with one card when time_shift is set to 0.
Some data can be found here:

Either the time_shift code is broken for the second card, or the time to read in the data cannot be shortened, or the calculation time to decimate the data cannot be shortened (with existing code).
