Looking for actual BP drop rate matrix

[DeletedUser21941]

Some time ago (years ago) I remember finding a post that had "percentages" for m/p certain buildings by age. For instance, it said something like, and this example is completely fictional:
Bronze Age:
5% chance to get Zeus BP for polishing flowers
0% chance to get Babel BP for polishing flowers
1% chance to get Zeus BP for motivating Fruit Farm
5% chance to get Babel BP for motivating Fruit Farm
etc, etc, etc,

Anyone know what I am talking about, and if this post still exists? Has it been rendered useless due to changes in the game over the past couple of years?

Thanks!

I've seen multiple versions of things like that. I am convinced they are all bogus, the drop rate is the same no matter what type of building you pick.
