user actions generally are related to a specific action a user made.

Would this make more sense as a binary histogram which would record the
open_activity_controls_url state? As it is, there is no easy baseline (i.e. to
see how after open_activity_controls_url==false occurs).

Maybe you could share more what you're trying to learn.

I spoke to the PM. We would like to know the number of times the user checks the
checkbox and goes on to complete the signin. So ideally, we would like to record
this action before/after signin_signin_withdefaultsyncsettings and
signin_signin_withadvancedsyncsettings to use in User Action Sequence graphs.
And also, we're not interested in knowing if they simply check/uncheck the
checkbox. I think the way the action is being recorded here achieves this goal.

I'm not sure I entirely agree. If you want to know how often people are checking
the checkbox, it's much better to have a baseline so you can understand the
number. Absolute counts are generally not as useful since it van vary with the
population - this is why we encourage all metrics to have baselines when
possible, and baselining by the number of times people complete the flow seems
natural.

You can leave the action you added so you can see what percentage of
withdefaultsyncsetting ended with the checkbox being checked for the sequenence
analyzer, but I think it would be better to also have a histogram which measures
what % of the time the checkbox is checked.
