Override the Simulator's default "Smart Recording"?

You mean in the .fit generated with a CIQ app?  I never checked, but I thought the generated fit would be 1 sec and not smart, unless you were playing back a .fit was recorded using smart..

Yes, the .fit from the CIQ app in the Connect IQ Simulator.

And no, it doesn't: Here are some results from today's test decoded to CSV for my app.. As you can see, the seconds are not continuous:

I wasn't "playing back" a file. I was using the "Simulate Data" option.

I can confirm that the Unix timestamp generated by the sim via Simulation>FIT Data>Simulate Data does not 1s recording.

I have already searched the sim for a 1s setting, but this is obviously not possible. So to test algorithms, I'm currently manually editing the .fit file to a 1s recording and then playing it back with the sim and output results to the console using println().
