LGTM with either increasing the sampling interval or using the new 1s constant.
| # Exponential damping factor (see below) | ||
| # Seconds per measurement | ||
| SAMPLING_INTERVAL = 5 | ||
| # Exponential damping factor for a sampling interval of 5 seconds (see below) |

Thanks for the comment, I should have had this in here originally. I think it might be worth adding a little explanation like:
# Calculated using 1/exp(5sec/1min) = 1/exp(5/60)the source is https://github.com/torvalds/linux/blob/master/include/linux/sched/loadavg.h#L21
If you feel like 1 second is better, then the new constant would be 0.98347145382161748947374 https://www.wolframalpha.com/input/?i=1%2Fexp%281%2F60%29
