Not accusing jaysblue of lollygagging but I feel this is a good time to reiterate anyways:
The 12 hour window is in place to accommodate life. Work, commitments, family stuff, constipation, scheduled masturbation, and furry parties (spanky) will get in the way and people will end up taking the entire window or missing a pick entirely from time to time. It happens.
However, the expectation is that if you are at your computer within your twelve hour window, you should be making a pick! Everybody has lots of time to prepare for upcoming picks. When the clock is on you, if you are at your computer, you should be picking! There really aren't any great excuses for chewing up multiple hours of your 12 hour window for the sake of deliberation, especially during the evening, which is a prime window for us to spin off a bunch of picks.
I knew my two first round picks would come up while I was at work the other day, and I work in the field with nothing but a constantly dying smartphone with shoddy reception. Nonetheless, I made a shortlist of names the night before and when my pick came up around lunch, I was able to rifle off two picks from the bush while 64 mosquitoes tried to carry me off to Mount Itch.
This is not an enforceable rule or anything, and it never will be, but understand that if you are going to be visibly online during your window and not make a selection, then others in the league will get annoyed. You might be frowned upon. Also keep in mind that if you're going to chew up a few hours of prime picking time during your window for the sole sake of deliberation, that might be the difference between someone shortly after you making a pick before work or bed, or missing their window entirely.
Be considerate of others and be prepared for your upcoming picks, please!
I love you all! This league is amazing! Let's keep it amazing.
