[OC] Visualizing my training stress balance (ATL/CTL ratio) over time

This visualization is based on my personal running data.

ATL is calculated as a 7-day exponentially weighted moving average of training load, while CTL uses a 42-day window.

I plotted the ATL/CTL ratio to explore how sudden changes in training load relate to perceived fatigue over time.

Curious to hear if others here track similar metrics or interpret this differently.
