My understanding is that the Team Familiarity meter is a reflection of the sum PLAYER knowledge, rather than the coach's understanding of the plays in his own playbook. Different coaches (even those with the same style, ie West Coast) will have access to different plays, but won't call plays that you do not 'check off' on.
This is correct. You can see what each player on your team knows about your playbook in his "plays" tab.
The players study all the plays in your coach's playbook during training camp, then they study the plays you have selected for the game plan during each game week. They also gain some knowledge of the play every time they are part of the play during a game. If you have a similar game plan every week and don't have a lot of roster turnover or change your head coach you shouldn't take too long to get high familiarity bars for your most-used plays. Scouting plays usually takes longer because you don't necessarily see the same plays from week to week.
