bs or ps

How often would you find yourself in a power struggle or a block struggle?. I'd probably say roughly about 20%-30% of the time I play and depending on what I am blocking (whether I am bsing a beam or a detachable attack such as big bang, deathball etc). Power Struggles rarely happen for me...

Sometimes when I am PS against someone who is PS or BS against my beam, and I use all of my ki up the beam just keeps going until it hits the edge of the map killing the other person. Problem is that the beam doesn’t explode because it appears to stop moving and I am still attached to it...
