Yeah, if you're going to fish for grabs to CG, at least use more jabs to set the grab, rather than trying to dash or shield grab mainly. It's pretty easy for me to bait shield grabs out of most of the people I play, so I can get a really good punish in for you using it so often when you're trying to land grab. OoS jab (jab) -> grab is much safer than shield grabbing for Falco, but just try to switch that up more overall.
I only felt real pressure from you when you got me in a CG. I spotdodge to avoid grabs or certain moves that would push my shield too far away for me to punish with jab or a grab. If I'm under pressure, I do my hardest to get offensive and turn it around, as any player should do unless they're using a really camp-centric character. I wouldn't dodge much if at all if you were using someone with a less intimidating grab game. It doesn't have much to do with pressure, personally, but more-so to do with avoiding something that puts me in a very disadvantageous position. If you have me grabbed, you can throw me offstage. Ike's recovery is pretty tripe if you are competent as to how to deal with it/bait either of his options or offstage offensive/defensive tactics if you think you've applied proper pressure.
Falco's jab is really useful for punishing a myriad, even punishment from the other player themselves. I don't feel like you use it enough. It's versatile and can link into quite a lot, most notably grabs, tilts, aerials, laser retreats, and itself. It's pretty vital to playing Falco. Try to replace most of your dodges with jabs/turnaround jabs, grabs/turnaround grabs, and short-hopped aerials. You'll do a lot better on the ground, I promise you'll see a big difference in how well you do.
Also, that tech you got on Yoshi's Island after my spike was top notch.
Top. Notch.
