Up to 4:30 lengths per break now? Crikey.
It again could be perception, but it seemed once upon a time you could count the number of then shorter 30-40sec slots before un-muting again to 4-5 (or so I thought) to hit the 2/2.30 mark.
You'll also note the new norm is put credits in a PnP window (a change after cutting them off and people complaining.. not that they are visible/readable!) and scroll them fast so they can either switch straight to the next one. Or throw another break in between.
