 This one starts to get interesting since it requires parsing the instruction
 input. Since the assembly version knows exactly where to find everything, it can
-be hyper-optimized. The pinocchio version performs very closely to the assembly
+be hyper-optimized. The pinocchio version performs better than the assembly
 implementation!

 Note: `create_program_address` consumes 1500 CUs, and `invoke` consumes 1000, so
 we can subtract 2500 CUs from each program to see the actual cost of the program
