An accent (for example the first beat of bar) needs to be really short. Now the accented best is extremely broad. No timing whatsoever. Practically an upbeat is blurred with downbeat. (It takes two for tango, of course, but how about tea for two?)
This is really satisfacrory for rehearsing free pulsative music.
To be accurate the pulses and accents needs to be much shorter. Way shorter. And with more impact.
