These changes look mostly good - I think we should change the metric naming slightly as I mentioned in a comment inline.

I wonder if this makes sense? This read method is going to be called for every read into a file. Eg if something is reading a file 1 byte at a time, it could be called 100's of times. Would it make more sense to increment just once when the proxy class sets up the reconstruction reader? Eg in createBlockReader() in the same class?
