Congrats on getting out of Open. Hey, if it makes you feel any better, Koji and I are still in Excellent Standard. We've been there, OMG I just looked

we have been there since July
2011!!!!

That's when I got our third OA leg. Jeez. That's just sad. And no, I don't have any Q's either.
I agree with others, that with the JWW run, it looked like you turned sharp which pulled Bailey into you. No worries, it's just something that you gain with experience and how your dog reads you. Koji used to read everything I did. Either I'm better, or he stopped reading me so literally. LOL.
May I make one suggestion. And if you have something like this already, nevermind. I saw on your STD run you were having some issues getting Bailey back into the weaves. I saw that you were backing up, to give her room, then sending her through. I know, with Koji, he would never go in right when I did that. I had to learn to circle him around (meaning, I'd get him on my side, walk away from the weaves, then circle back around to face them), then send him off (worked every time after). Or, teach Bailey to go around and behind you (like ortegah/Heather does with Trax) and then send her off. For me, the backing up, just never worked.
You guys looked great out there! I can't say the nerves go away, but it probably gets easier over time. I still have massive nerves, especially when I'm trying to work on something.....like Koji's 2o2o. I try to calm down, but ugh, it never works. I started taking Koji's L-theanine, LOL. Didn't do much.
ETA: It IS a very different feeling running Excellent/Masters. I think for myself, going from an average of the 15th dog, to the 40th, was huge. It added a lot to my stress because I had to watch the ring constantly to make sure I wasn't passed up. 40+ is a long time to wait. I was once the 75th dog. Yikes. And then, you run JWW in the AM (oh wait, I run 16", I run first thing in the AM). I liked that because I'm half awake, lol. No time for nerves. Now with T2B and FAST before everything else, my nerves start acting up. You're not alone. Gosh, I've been doing this since 2009 and I still get nervous. Especially when it's an important run.
