Ultimate Ski Jumping 2020

Simply play 10 games on realistic style. To change your style, click competition, then player configuration. Once in the configuration tab, chose player 1 on the left hand side. From there, change the jumping style to realistic. This is the same screen that you can change your outfit for that achievement.

When jumping/landing on realistic, you will need to hit both bumpers at the same time. It is supposed to simulate both legs for the jump/land.

I loaded up a solo match from the competition screen and chose Poland K16, as it is only two short jumps.
