Some people just attach the sensors above the opener on a board and pointed at each other so they are up and out of the way, instead of actually installing them the way they were designed to work.
Did they even call stalling in the Block match? All that kid did the 3rd was go backwards and run and I didn't see them call it once. If other way around Block is getting hit 3 or 4 time easily!!
He actually grew up in Denver and didn't move to Waverly until 8th or 9th grade to get better workout partners to practice with and can't blame him for it either.
