First, the number is not in percent... it's just 194, not 194%.
Second, maximum effective accuracy is 110... there is no difference between 110 and 194.
Third, maximum effective accuracy doesn't guarantee a hit... it's just smallest deviation... but can still miss, especially when the trajectory is very "fragile" with many obstacles along the ideal path.
... just move to a different position and try again.... don't try from the same spot again, you will continue missing.
