For me it's only a 50% spalding because feathers of the neck are just beginning to change .Here you can see every feathers one by one ( By the blue peacock we don't see every feather only a blue mass!).
With over green blood each pen will have an eye more and more visible.
Now the name is High %tage spalding because with all the new mutations only a few of them are emerald .... blue and green mix .
The emerald spaulding nomenclature is well overused in my area for less superior birds.
