Hello Graeme!
Not really. There is only one A2B table computed, and it's the smoothingof that, that you are changing. All the different B2A tables are created from that one A2B table.
By the way, are you making smoothing of input measurements itself? If so, is it possible to make a key to export smoothed measurement data to ti3 file. I think it would be useful feature to see the difference between original and smoothed measurements, this will help to make a decision about smoothing level.
