How does Skritter determine which lists to add words from when?

I've got a lot of lists I'm adding from right now but, even so, with nearly 300 items added today it seems weird that some lists added no vocabulary while others added five or ten words.

Each list takes turns when it's time to add a word. If you've got items in the queue, it takes its turn, too. The turn is not remembered between sessions, so if you revisit the page, it picks a list at random to start with.

There can be complications in terms of how many words you see added from a list depending on whether the words or characters in it are entirely new, being reactivated after deletion, are partially new, etc. But that's how it should work. If you think it's totally ignoring some lists, can you say which ones?

I'll pay closer attention this session but my last session definitely didn't get any words added from the Noodle Menu and had lots of words added from the Periodic Table of Elements.

Oh, I just took a look. Dearie me, you do have a lot of lists going! Skritter only loads words from 20 of the lists, picked at random--hard to say which it has picked, but it looks like the Noodle Menu list isn't getting picked right now.

I'd recommend focusing on somewhat less than 20 lists at a time to cover them all.

By and large (physics, periodic table, ecology lists notwithstanding) I already know the words and can type them / read them. Just that my writing ability is embarrassingly bad for a professional translator.

I was getting bored having either only easy vocabulary (function of word frequency lists) or single area vocabulary (fruits, bathroom, restaurant dishes lists). Having random additions from _all_ kinds of lists seemed the best solution.
