Free Will inside the multiverse.
Benjamin Libet measured the so called electric Readines Potential (RP) time to perform a volitional act, in the brains of his students and the time of conscious awareness (TCA) of that act, which appeared to come 500 msec behind the RP. The “volitional act” was the by free choice pressing on an electric bell button.

The results of this experiment gives still an ongoing debate in the broad layers of the scientific community, because the results are still (also in recent experiments) in firm contrast with the expected idea of Free Will and causality.
We would expect that based on causality the Time of Conscious Awareness (TCA) ALWAYS comes before the electric RP, which is found to be present in our head because this would be the proof that we humans are equipped with the free will to press on the button at the moment WE are also conscious to do that!!!.
HOWEVER Libet (and later all other researchers) measured the opposite for most of the students. Only a FEW students reported to have “PREPLANNED their ACTION” (RPI in the next figure)

A causal but weird Multiverse solution.
If we assume that we are living inside one of the 12 postulated copy universes, which are each others observer by “mutual entanglement” to trigger randomly and alternating the collapse of the copy wavefunctions, (thus also to trigger a volitional act, like Libet's subjects) in the other 11 universes.

Then as a consequence, we may expect that only a small part of the students will report to have had the conscious intention to act earlier. Thus in the case of 12 entangled universes we may expect that 1/12 part or 8,3 % of all (human) timing of conscious intention to act, will show a reversed timing sequence between the so called Time of conscious awareness (TCA) which will come BEFORE the electric Readiness Potential (RP).

Indications of those percentages, are already found by Judy Trevena and Jeff Miller (Otago university NZ). See:

-------------------------------------
The Benjamin Libet percentage results of pre-planning (RPII) are very poor quantified in his and later experiments.
Reason to do it again with more precision on the readiness potential percentage differences between RPI and RPII..

If humans are entangled cooperating decision makers inside the postulated 8 or 12 entangled but separated universes, then for every decision we need always only one preplanning test-person who pre-plans his choice. The other 7 or 11 test copy-persons are only able to follow OR REJECT this decision.

As a result we may be able to measure (in the future) the number of copy universes involved, by counting the average percentages of preplanning persons in test situation like the Libet test..
For 12 universes the RPI percentage will be 100/12=8,3%. For 8 universes RP I will be 12,5% For RP II it will be 91,7 respectively 87,5%
