That's one of the reasons I moved to Sufferfest (SYSTM) for interval training because their benchmark test measures your 10 sec, 1 min, 5 min and 20 min power to build a more comprehensive power profile with which to set interval power targets. It works well, but the benchmark test itself is not something you would want to be repeating bi-weekly! So they do also have a ramp test for interim progress checks, which in itself is more sophisticated than the simple Zwift ramp.
The 4DP test? I'm planning on doing that sometime before Christmas, using the 14 day free Systm trial!
