Fun idea
One thought would be to use Publish/RefCount on the sources so they are the same streams. For example "meatsSource" currently will be subscribed to three different times (if I counted that right) so what's being logged I don't think is technically what makes it to the end. If you log the n from the zip
You'll see 3 of each count showing up
Using a Logging extension might help clarity

It's the one time you can have a Do and you won't get yelled at :-p
so something like
