Is there a consistent way to SJC on stick? I always get regular jump cancel seismos

…despite the input display showing me doing down then up. I never had this problem on pad or even on keyboard in my kaillera days.
I have not found a consistent method of SJC cancelling on stick, though, it seems like I’m going the same thing when I successfully SJC and JC. It might not help that I play mostly online nowadays, though.
