I had a bit of a play with that and used a record that was already a close match to the target spectrum so that I could use a tight tolerance. I think I had a tolerance of 0.15 and it would converge in ~10 iterations over a relatively small period range. It just appears that it is not matching very ...

Hi, thanks for the speedy reply.
I have tried the tighter tolerance noted below and still get the same variability. Also, as you note, I have only been comparing this for the range between the max and min periods that I have specified for matching.

Is it possible to complete the spectral matching against a user input time sequence for the spectrum? I have come across the change in time step under Settings>Response Spectra, but I am still finding that there is a lot of variability in the matched spectrum when I compare it to the spectrum ...
