Best practice for tophub updates

Hello,

when submitting updates to tophub, what is the best practice for the diff? So I took the old file, my new tuning results, concatenated them and then used tvm.autotvm.record.pick_best. I noticed, however, that it would update the version TVM tag for the pre-existing records, inflating the diff.

What is the best way of dealing with this? Should pick_best (optionally?) retain the original record data?

Best regards

Thomas
