You can find it in the 27 years of the RVator starting on page 363.
In a nut shell, there was no evidence found to indicate that the use of strakes had any influence on stall speed. They did effect the pre-stall buffet by reducing it and making it not occur as much before the actual stall occurred (not beneficial in most peoples opinion).
What was confirmed is that flying without gear leg intersection fairings will
negatively effect stall speed.
