For number 1 having one fare all the time does simplify use of the system. However, you inspired me to play around with the fare calculator and it looks like the only people who would be having fares reduced are traveling during peak periods and currently pay up to $3.30 per fare. At $3.45 there's a fare increase. For off peak travelers unless you're currently paying the base $2 fare, in which case it will stay the same, you will see an increase (even the $2.05 fare goes up).
