Thanks for tracking this.

Assigned to Marti who implemented it.

I guess we need to make the following 4 parameters configurable:
- Auto-Always Threshold (default: 5)
- Auto-Never Threshold (default: 7)
- Max number of Auto-Always (default: 2)
- Max number of Auto-Never (default: 2)

Thoughts?

also. please advise if we need to make the default value of Auto-Never threshold bigger.  thx!

Those 4 params LGTM. With regard to upping the auto-never number, I really think we should, I'd suggest to 10.  Consider these beta metric: 31% of users are clicking "Cancel" on the auto-never snackbar. That's compared to only 5.5% of users who are doing that for auto-always. 

cool. Thank Yana!

We could configure those parameters in Finch experiment now.
