Yes without marker it is hard to interpret. Here is the marker. FRC power is extensive anaerobic according to iLevels and FTP is aerobic contribution. In WKO VO2 max is called FRC/FTP.
And for values - the dashed line is a value so for example (in my case with different chart data than this) 2 min power is 75% aerobic, 5 min power 88%. So they do not overvalue anaerobic that much.
