Potato sorting by size

May seem to indicate marginal levels of OCD but I thought it important to sort the potato harvest into size order (the substantial harvest of the Nicola variety in particular).  Not completely from smallest to largest but just into general categories, to make it easier when cooking something to pick the best size.

4 categories; tiny - not sure what for; small -  for salads etc.; big - probably cut in half before cooking; massive - for baking or chips.

Very satisfying half an hour (if only slightly worrying).

Here's the results showing a nice normal distribution curve.
