A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
A player, 8 June 2009
I searched the Rulings and went through the Comprehensive Rules, but couldn't find anything that seemed relevant to this question. The Student says:
The Student has +1F while you control The Sensei.
In a recent game, we assumed that this means that each copy of The Student you have in play gains +1F if you control any number of copies of The Sensei i.e. his force would always be 3F. However, we had some discussion about the possibility that The Student could gain +1F for EACH copy of The Sensei you control, so if you, say, control three copies of The Sensei, The Student would be 5F. We settled on the former because we assumed that if it meant "for each copy of The Sensei", that's what it would say. However, I thought it would be worth checking to confirm. Were we correct i.e. it's just +1F for any number of copies of The Sensei you control and not +1F for each?
Thanks.

The force bonus is +1F regardless of how many "The Sensei" cards you control, as long as that number is greater than zero.

+1F only.
It's one bonus with one condition ("while;" http://rules.l5r.com/Glossary_W#While), not a fluctuating bonus (which would be "for each;" http://rules.l5r.com/Glossary_F#For_each).
