All day ACBL games

[gbsmith4]

I'm curious if others have found the same thing: In the all day ACBL Robot games, I struggle to get much beyond the mid-50%s. Yet, in the 1 hour ACBL robot games, I'm consistently higher.

 

My thinking is that in the all day games, there is note-taking, writing down the cards played, etc. In short, it's more like an open-book test of bridge.

 

In the one hour games, there's obviously little or no room for messing around, so the scores are a bit more "pure."

 

But, it may just be my imagination. Thoughts?
