mk.32, two compressors are not legal in 2014 and actually never have been even before we allowed off board compressors. The "one and only one compressor" language is very specific.
Al,

As you prepare for the 2015 season, I think you might want to revise the wording on this rule to make your intent clearer. Based on the comments in this thread alone, there seems to be significant confusion. Maybe it's because the ruling seems to be a bit counter-intuitive in comparison to what we're all used to.

So a couple of questions for Al/Jon/Mark and any other LRI's on this rule based on what was written and enforced in 2014.

1. Is it legal for a team to alternate between multiple compressors during an event? i.e. Can a team charge with Compressor A after match 1, and then charge with Compressor B after match 7.
2. If #1 is legal, is it legal for a team to charge with Compressor A and then switch to Compressor B halfway during the charge.

Based on my reading of the rules and your posts in this thread, I'm thinking that both 1 & 2 are illegal. However, this runs contrary to how I've seen this rule enforced, and the interpretation of most people I've talked to.

3. If 1 & 2 are illegal, does this mean a team who blows their compressor during an event is now unable to use a compressor for the rest of the event?

This one seems a little silly, but based on "one and only one compressor" language, it makes me think that this team would now be out of luck.

If 1 & 2 are legal, I highly recommend that the wording be changed, so it's clear that teams are allowed to switch between compressors.

Anything we can do to make the pneumatics rules clearer for teams will go a long way in promoting their safe use throughout the competition.
