Estimated Time to Run model

[Sam Talkers]

Hi all, first off - love this idea in making ML accessible in sheets. It's a very cool idea. I am looking at a dataset that is about 20 COL and 4000 rows. I'm sitting here keeping an eye on it but it appears to be collecting examples for some time. Is there any reference available to better understand how long this will run until complete (based on row count/fields)? Perhaps some recommendations I missed in the instructions.
