This is 100% practical. I actually knew about this for a long time, months now but never published it because I didn't think it would be too useful but I've learned some things about safejump properties, and also saw that Bonchan was using the exact same setup so felt the need to publish it.
Very good when you're in burnout and/or just need one more hit, I have yet to see anyone block the crossup. Not hard to time but you can use it on non-DP characters for now if timing is an issue.
Congrats to DualKevin on making Capcom Cup.
