That's not the pattern I see when looking at the op-code/cycle chart. I recently implemented part of a C64-emulator in JavaScript and it seems very much like every step takes a cycle.

For example the instructions NOP(or CLI, STI, INX etc), 1 byte, 2 cycles. 1 cycle for fetching the instruction and one for executing the fetched instruction.

LDA addr,x seems to be pipelined a bit though. It's "AD lo hi" in memory and takes 4 cycles unless lo+x > 255, then it takes 5 cycles. The lo+x calculation seems to occur while hi is being read.
