You already got your answer, but to add a bit most times in statistics they round up for any overage.
If some test requires 17.423 people to complete, 17 is not good enough because you need more than 17 people. Due to physical constraints and unwillingness to berate someone as being less than a full person due to mental or physical issues, we have to go to the closest number that is more than 17, which is 18.
Due to extensive research done by the University of Pittsburgh, Spirit breaker has been confirmed as the hardest bash known to man. The research is as follows. Pocket-protected scientists built a wall of Slardar and charged a spirit breaker into it at 522 miles per hour, and the spirit breaker was unharmed. They then built a wall out of spirit breaker and sprinted a slardar moving at 522 miles an hour into the wall, and the wall came out fine. They then charged a spirit breaker made of 522 miles per hour into a wall, and there were no survivors.
They crashed 522 miles per hour into a spirit breaker sprinting at slardar. US east was powerless for hours. They time-walked a wall of faceless into a 522 mile per hour made of spirit breaker, and the resulting explosion shifted the earth’s orbit 522 million miles away from the sun, saving the earth from a meteor the size of a small Washington suburb that was hurtling towards mid-western Peru at 522 billion miles per hour. They shot a spirit breaker made of slardar at bloodseeker moving at 522 walls per hour, and as a result caused two flying courier to lose track of their bearings, and make a fatal crash with two ancient in downtown New York. They spun 522 miles at spiritbreaker into slardar per wall. The results were inconclusive. Finally, they placed 522 spiritbreaker per hour in front of a bloodseeker made of wall hasted at miles per slardar, and the result proved without a doubt that spirit breakers were the hardest bash of all time, if not just the hardest bash known to man.
The precious Peruvian Guano islands resources were depleted by the 19th century so maybe that is why every time you get pooped by a bird could be interpreted as “yes the Guano Era is back, we’ll be rich again.” Sorry I like history…
