I have done an experiment.
Actually, I conducted several experiments to PROVE the TRUE value of DOUBLE STRIKE BOOSTESSES in Modern War.
I have accounts with DSB varying from over 200% to about 50%.
For ALL of my accounts over 100% in DSB I was able to consecutively receive the value of the DSB for as few as 20 times, but NO MORE than 25 times.
I suggest you try the simple test, and share your results with the community.
My hypothesis is that DSB is nearly unlimited in PVP.
However, the effect of DSB is THROTTLED by some unknown hand
in MW.
