Here are a few of the details from the Wed. ride along with some other stuff from the Training Peaks WKO software.
The Performance Management Chart shows an "ATL" score which is the acute training load. This is a combination of duration and/or intensity.
The "CTL" score is the cummulative training load. More of a gradual build.
The "TSB" score shows the Training Stress Balance which will dip when you go to hard, too long, too often without the base.
If someone was more methodical about training they could use the chart to peak for events.
