Did an aspd test of dgs with quicken and running shot in 50dex increments. My ping is between 15-40ms.
Tool to measure ASPD: MPC-HC.
Procedure: Measure the total time between 1. Hit and 11. Hit on trainings doll and divide it by 10 for an average aspd. Did the testing twice and the average error was around +/- 0,1 HPS.
