It doesn't matter how many times I do certain flights, I can generally get better each time by remembering small quirks observed previously.
I also learn by moving boats of different lengths, some major changes in boating style can be beneficial with shorter boats.
....and it doesn't matter how experienced you are, you still make mistakes. ☺
Coming down Napton a couple of weeks ago, I forgot the bottom 4 locks keep a wave going as you open the bottom lock gates , and as I was closing the gates, watched Old Friends get very slowly moved out of jumping distance and had to jump the barbed wire fence on the offside and get muddy feet to clamber back on.
