         Generating a block template is a simple thing.  Ask for a boatload of information, and go from there.
         Important things to consider.
         The reserved space is 13 bytes long now in the following format:
-        |minerNonce/extraNonce - 4 bytes|instanceId - 4 bytes|clientNonce - 4 bytes|clientPoolNonce - 4 bytes|
+        Assuming that the extraNonce starts at byte 130:
+        |130-133|134-137|138-141|142-145|
+        |minerNonce/extraNonce - 4 bytes|instanceId - 4 bytes|clientPoolNonce - 4 bytes|clientNonce - 4 bytes|
         This is designed to allow a single block template to be used on up to 4 billion poolSlaves (clientPoolNonce)
         Each with 4 billion clients. (clientNonce)
         While being unique to this particular pool thread (instanceId)
