 # TODO: instructions V-Ext duplication analysis <a name="duplication_analysis">
 
 This is partly speculative due to lack of access to an up-to-date
-V-Ext Spec (V2.3-draft RVV 0.4-Draft at the time of writing).  However
-basin an analysis instead on Hwacha, a cursory examination shows over
-an **85%** duplication of V-Ext operand-related instructions when
-compared to Simple-V on a standard RG64G base.   Even Vector Fetch
-is analogous to "zero-overhead loop".
+V-Ext Spec (V2.3-draft RVV 0.4-Draft at the time of writing).  
+A cursory examination shows an **85%** duplication of V-Ext
+operand-related instructions when compared to a standard RG64G base,
+and a **95%** duplication of arithmetic and floating-point operations.
 
 Exceptions are:
 
-* Vector Indexed Memory Instructions (non-contiguous)
-* Vector Atomic Memory Instructions.
-* Some of the Vector Misc ops: VEIDX, VFIRST, VCLASS, VPOPC
-  and potentially more.
-* Consensual Jump
+* The Vector Misc ops: VEIDX, VFIRST, VCLASS, VPOPC
+  and potentially more (9 control-related instructions)
+* VCLIP and VCLIPI (the only 2 opcodes not duplicated out of 46
+  total arithmetic / floating-point operations)
