LSEQ/LSEQR were created for the scenario where you know the start and stop values and the step value is 1 or -1. If that's a good fit, then those commands require fewer arguments (and are 10-30x faster) than SEQ. Even if the step value doesn't match, they may still be useful if the input and output can be easily modified to make it fit (as in your above example). They do require the input to be in the form of integers, though. So if that can't be done easily, they aren't a good fit and wouldn't be appropriate.

Thansk for the input, and nice to see that slowly another library is being done. StephenG1CMZ I recommend you to see the library of DavidM to get some more inspiration!
