So you are the coordinator of your town's mega ice cream sundae social this year, and it is your job to plan the capacity required to serve the customers of the social. Last year, you identified the bottleneck station as the sprinkle station. You made the following observations in regards to the sprinkle station.

"Overall, $476$ cones went through the sprinkle station. $($I would expect the same amount this year$)$ There are $2$ people working at the sprinkle station, both doing the same work at the same time. The people are working at the station for the duration of the social, $1$ hour. It takes $10$ seconds to process each cone and $19$ seconds to set up for the next set of $20$ cones."

Assuming that you are able to achieve a $20\%$ capacity cushion this year, what is the difference between this year's and last year's utilization at the sprinkle station? $($enter response rounded to a whole number, ex $50)$
