Russia launched 6,583 long-range drones during the month, according to a compilation of daily reports published by Ukraine’s air force.

That was two percent more than the number fired in March, which was also a record at the time.

According to the data, Ukraine managed to shoot down 88 percent of all incoming drones and missiles.

This is interesting, but lacks context as the question is how many got through? Is the 88% nominal, or up?
