The testing options are all bats have to pass at 240
It is allowed that 220 bats have to pass at 220, 240 bats have to test at 240.
Why would a bat manufacturer want to allow 220 bats to be tested at 220 going forward? That would hurt their sales going forward and would just drive the resale price up for the older models that the bat companies are no longer making money off of. People wouldn’t buy 240 bats until all the 220 bats were gone and or wouldn’t pass. the buyers would just go through the 2nd hand market to keep using 220 bats that would be allowed to test lower. If the 220 bat has to test at 240 the assumed life expectancy of the bat is decreased faster than if it could pass at 240 and should increase bat sales.
Seeing as bat companies are still releasing 220 bats and the decision hasn’t been posted seems to lead that the manufacturers have stock that they want to sell before a decision comes out that all bats will have to pass at 240 bc the two test option doesn’t make sense for the manufacturers money wise.
I have no inside knowledge and could be wrong and this is all from a big picture view I’m sure here and there tournament testing will do their own thing.
