more daytime questions

[arizona]

Like a lot of people I seem to do better playing in the evenings than during the day. I usually don't start playing until 6pm EST, trying to play on tables where the avg pot size is at least $30 (thats at party 3-6 6max tables). So here's my question: If I can find a table with the same avg pot size at say 3pm EST it would play exactly the same as the tables do during the evening wouldn't it?

Tables like this aren't that hard to find, but the general consenus on this forum seems to be to play only during the evening so I am always a little skittish about trying to play earlier even if the games seem to be exactly the same. Am I missing something here? Thank you for your thoughts.
