You will never need an IDA, a burette, stopwatch and a set of scales is all you will ever need
I hear what you're saying there, Sean. However, I must admit that I find the IDA graphics software invaluable in being able to (literally) see what is going on, especially when comparing the performance of pumps of the same type, and when checking out pumps of the older Argus/Codan and Arcomed varieties (that is, watching to see if the doors hold the pressure, if you know what I mean). The IDA doesn't even need to be calibrated to the
n-th degree - it's the shape of the "waveform" that is of interest there. Rising sawtooth
versus ragged zig-zag that fails to reach occlusion pressure levels,
etc., etc.
