Paranoia 270 heavy, 290 Oni help!!!

[spidersilva]

OK this is the problem. I could beat max 300 on heavy no problem, the legend of maxx, maxx unlimited, max 300 super me mix challenge also no problem, all on foot. But I have trouble beating paranoia survivor 270 on heavy and paranoia survivor 290 challenge. It's the last part of both of the songs where it's non stop arrows. Even though the last part of max 300 super me mix is constant arrows, I find that these arrows are easy but not the last herd of arrows on the paranoia's. It's like I have to hit 2 arrows with the same foot, yeah I play ddr on foot pretty weird or orthodox. Any songs where I could practice stepping the right way so I could get used to it. I know Afronova is one of them and can't stop falling in love speed mix is another song.
