Brainlearn question

should I turn concurrent experience to true if i am using brainlearn under cutechess cli?

Concurrent Experience
Set this option to true only, when concurrency > 1
the saved experience file name will be modified to something like experience-64a4c665c57504a4.bin (64a4c665c57504a4 is random).
Each concurrent instance of BrainLearn will have its own experience file name, however, all the concurrent instances will read "experience.bin" at start up.
