* Output: | |

* T | |
* #1:TTT -> 2 ticks (removed echo tick) | |
* #2:TT -> 1 tick (removed echo tick) | |
* #3:TTTT -> 3 ticks (removed echo tick) | |
* #4:TTT -> 2 ticks (removed echo tick) | |
* end:T% * | |

* One tick has to be removed for each section, which is the echo invocation. | |
* Thus, only variant #2 is faster by one tick... | |
