Section Tractor Spacewalker or Microship is a bit confusing.

• Spacewalkers and microships are considered Size 0, so the formula should be just Enginering vs. Distance + 2 x Speed (the + 2 x Size part is always going to be 0).
• Spacewalkers' Speed is presumably 0, but it should perhaps be noted.
• More puzzling, there's a discussion of the target number of spacewalkers (alone o linked), which is interesting if someone fires at them, but not relevant for tractoring.
