This is a duplicate PR because I couldn't figure out how to fix the original one. The idea is from @31m059 with formatting recommendations by @snicolet. See #1940 for additional information.

These 5 arrays are simple enough to calculate real-time and maintaining an array for them does not help. Decreases the memory footprint. This seems a tiny bit slower on my machine, but passed STC well enough. Could someone verify speed?
