- FPUT is algorithmically faster than LPUT
- Having two "make" instructions in the loop generated unneeded garbage.
While LPUT might have been clearer, the fact that there was two instructions, one for the frequency and one for the duration was hard to see. To help clarify what the REPEAT instruction is doing, I added an explanatory sentence which shows the gist of what list is being created. Preserving the ascending tones with LPUT would have made the math unnecessarily complex, so I made them descending.
