You are right upto some point.24 may bgc complete 26 may copr update.
But this method of ppr is very delayed, other one is good in which copr doesn't update and direct ppr email comes
The method is still same as before. This tracker is just a new medium of enhanced information being visible to applicant.
My only concern is in my case all stages are completed on 29 may but COPR number is not issued.
