Getting cat-faced tomatoes late in the game

[cythaenopsis]

From what I've read, tomato cat-facing (weird oblong shapes) tends to happen when pollination occurs at cooler temperatures. I've also read an ambiguous reference about them being "disturbed". What exactly does that mean?

I hadn't experienced any cat-facing issues with my Black Krim plants until about a month ago, so no cooler temperatures were at play. I started to notice a few weird looking tomatoes appearing, like these:



Unfortunately, one of these shown ended up suffering from BER and I had to pluck it off.

My question is... if I use an electric toothbrush to help pollinate tomato blossoms, would accidentally "buzzing" a flower that had already been pollinated end up encouraging the production of a cat-faced tomato?
