I thought I'd post these photos to show what a lewisi with a very small amout of caymanensis should look like, not a caymanensis or a cuban with a little bit of lewisi in it. These are 87.5% minimum which means they could actually be 93% or higher. I included the photo of the pure specimen for reference, so one can see that we "lewisi" keepers should strive to keep our stock as close to pure as possible.
