In experimental tasks, parallelizing does not provide the same gain in success probability as accelerating the process of prototyping.

Building prototypes in parallel does not provide the benefit of a feedback loop, as the iterative process does.

Let's say you have a 10% probability of success on the first attempt, which improves by 40% after each experiment (to 14%, 19.6%...), and you have resources for 5 attempts. The chance of getting at least one successful solution is: parallel ~ 40.95%; iterative ~ 72.19%
