It's not a wind up. A normal egg isn’t spherical at either end - it’s an ovoid with continuously changing curvature. Even the rounder end isn’t a hemisphere, which is why standard egg cups rely on friction rather than geometric fit. That's by the by though - I'm making an egg cup that will fit a spherical egg perfectly, as my (now rotted) round egg does not fit in a 'normal' egg cup (as demonstrated by my tests). Pointless - probably. A wind up - absolutely not.

Spherical enough was what I meant.
You've obviously got more and better data than me though.

Thank you. I conducted my exhaustive experiments on 2 normal egg cups, although one was a double egg cup, so really 3.
