Pattern - Minimum Tile Size?
I'm making pattern swatches of very small objects. If I make the tile size too small I can't get the spacing close enough.
For instance, these dots are Ø0.1mm and the desired tile size is 0.4 x 0.4mm. However, the pattern wizard won't let me size the tile any less than 0.7056mm.

I realize that I can achieve what I want if I start with more opjects and a larger tile size. I'm wondering why there's a minimum tile size and if there are any other rules to consider.

Thanks
