Nice fruit set on those! Funny how far ahead those are compared to my Romance cherries.. mine are at the point when the blossoms are dropping and the cherries are becoming noticeable, but no bigger than peas right now.
My pattern of fruiting has been a bit different than yours. Two of 4 plants produced a few cherries each back in 2013. In 2014 I got maybe 7 pounds from the 4 bushes. In 2015 the production was actually a bit less than 2014 although all 4 bushes did produce some fruit, Carmine Jewel the most. This year it so far looks like a really good fruit set on all bushes, but I know those young fruit sometimes wither and fall in big numbers so I'm not clearing space in the deep freezer for the cherries just yet.
