Okay, what I did was I sat down with pen and paper, I found a date and time with Flawless Special for a Deino that was on frame 5, I walked 128 steps (advancing the frame to 5, as I had 4 guys in my party), I sweet scented, and caught the pokemon. Determined the nature, tried again, chattering once, then again, chattering twice. I determined the next Modest was 17 away, and after about an hour using the wrong input time, I got a female Deino, 31/27/31/31/31/31, Modest on the first try.
