The bottleneck on that is data interdependency of your algorithm. If you break it in 6 or 10 instructions, the data dependency stays the same.

(Of course, you can add unnecessary dependency with a badly designer ISA. But it's not a necessary condition.)

There's still a limit to how many instructions you can decode and dispatch every cycle, even with zero dependencies. There's also definitely dependencies in the example where you're computing a memory address to access a value.
