"If a GEAR set corresponding to the next sequential unengaged ROTOR..." implies that any rotor past the next sequential unengaged rotor isn't going to accumulate any rotations at all. Which only makes sense. Which further shoots down plans to prerotate a gear set, because only the next gear set will accumulate rotations. So there's no point to spinning up rotor 4 unless 3 is already going. And if 3 is going, you're not spinning 4 without a full gear set, at which point you spin it up completely.

The only reasonable case for placing gears out of order is a highly choreographed autonomous, as suggested by Siri, and by me in other threads. Possibly also disinformation relating to your total gear count as well.
I'm having trouble reading the new TU as definitively saying out-of-order turns don't count (even assuming actual engagement is sequential). To re-requote it with my emphasis: When a GEAR set for ROTORS 2, 3, or 4 is complete, a CRANK, a handle located with the first GEAR in the set, can be turned which engages the corresponding ROTOR. It takes three (3) full rotations to engage the ROTOR. If a GEAR set corresponding to the next sequential unengaged ROTOR remains idle for more than ten (10) seconds, the rotation count resets to zero (0).

And Q82 (in part): "ROTORS only start if GEARS are installed in ROTOR order." In other words, you won't be able to start ROTOR 4 until all other ROTORS have been started, etc.

As evidenced by the "in other words" of Q82, this is not a particularly tightly-worded section. (Requiring gears to be installed in rotor order is not in fact the same thing as starting rotors in order.) I suspect that HQ hasn't yet realized that this is of legitimate importance for some teams. As I read it now:
1) Rotors must be started in order.
2) A crank can be turned when a gear set is complete.
3) Rotation count resets when the next unengaged rotor has been idle for more than 10 seconds.

I don't think that (3) explicitly means rotations within those 10 seconds while that rotor isn't the next in sequence don't count. My reading of the logical flow is ambiguous across any of the following Step 5s:
Step 1 @ t=-3 Place Gear 1 in Rotor 2
Step 2 @ t=-1 Place Gear 2 in Rotor 2
Step 3 @ t=0 Turn Rotor 2 crank for 2 rotations
Step 4 @ t=3 Place Gear 3 in Rotor 1
Then:
  • Step 5 @ t=6 Turn Rotor 2 crank another rotation and engage Rotor 2
  • or Step 5 @ t=6 Turn Rotor 2 crank another rotation but cannot engage Rotor 2 because previous rotations didn't count
OR
  • Step 5 @ t=10 Turn Rotor 2 crank another rotation but cannot engage Rotor 2 because it is more than 10 seconds from its first rotation
  • or Step 5 @ t=10 Turn Rotor 2 crank another rotation and engage Rotor 2 because the prior rotations count and the clock doesn't start until Rotor 1 engages (such that Rotor 2 is next in sequence)
OR
  • Step 5 @ t=14 Never receive Gear 3, and remove Gear 2 from Rotor 2 to install in Rotor 1, engaging Rotor 1.
  • or Step 5 @ t=14 Never recieve Gear 3, and remove Gear 2 from Rotor 2 and install in Rotor 1 but don't get points for engaging Rotor 1 because you violated the paragraph about Figure 3-13 (despite HQ's interpretation of this clause in Q82).
  • or Step 5 @ t=14 Turn Rotor 2 crank another rotation and cannot engage Rotor 2 (because now either way you're outside the 10-second window)

Trying to boil this down into a Q&A, I'm thinking:
1) It is understood that GEARS cannot be removed after a ROTOR is engaged. However, can a GEAR be removed after a ROTOR is rotated but before it is engaged? Does this differ if the rotating is less than a full revolution or is accidental or strategic (in the estimation of the referees)?
2) It is understood that ROTORs must be engaged in ROTOR order. Must GEARS be also installed (placed without rotating) in ROTOR order? [A82 seems to interpret the manual p23 this way, but the manual still says "installed" rather than engaged or rotated.]
3) If GEARS need not be installed in ROTOR order, can ROTOR N be rotated (for accumulation of the required 3 rotations) before ROTOR N-1 is engaged, assuming the third rotation and engagement of ROTOR N still occurs after N-1 is engaged?
4) If ROTORs need not accumulate rotations in ROTOR order, does the (10) second idle window from TU6 start with the first rotation or when that ROTOR becomes the next sequential unengaged ROTOR?


Good point about deception regarding the number of gears you still need. My head was still stuck on autonomous.
