i swam: 50back:35:80(pb0.8s)happy 800free:11:13(pb6s) also happy but i didn't go all out

So I had a meeting this weekend and I had to swim a 200 fly. I did 2'54 in the morning in long course (my time in short course is 2'50) and I had to do it again in the afternoon, in final B. And my coach told me that I could do 2'50 if I change a little bit my second 100. The thing is I never did better on my final than on my morning race (or maybe 1 sec better) so I wasn't sure about that but I didn't telle myself it's impossible and put my mind into it, ate well at lunch, took a little nap, drank water every 20 mins, warmed up well... An I actually did it ! (During lunch break I was literally saying "I'm going to do 2'50" every 30 sec 😂, maybe my brain would understand it who knows?) In my opinion 4 seconds between the morning and the afternoon is a lot 😭. So I was the second one in my final, and the first one in my category so I' m a regional chapion at the 200 fly now 😂🥳🥳. And another great thing is my reaction time that was 0.73 in the morning and 0.54 in the afternoon (I rlly wanted to do 2'50). So now my next objective is 2'37...
