So I was doing some reading to understand why your blues do not follow the typical color ratio. The best I can figure out is that standard tables are based on "pure" blue strains without "interference" from other colors. Based on the coloring in the male you show above, my guess would be Red is involved in the interference as well as who knows how many other colors. White can also influence the expression of Blue. Since there are so many patterns I have seen in the pics of your birds, it may be pretty hard to sort out a good predictable pattern. Interestingly, I see the red ticks of color in the splash and blue female I have too.
