Training Rate Table, Page 107: Improving a skill group: New Rating x 2 weeks
Page 105: Skill groups are improved at a rate of [new Rating] x 1 month
Training Rate Table: Are the skill ratings the new ratings, or the current ones? Does it take 5 days or 5 weeks to raise a skill to 5? This doesn't seem to be addressed anywhere. The absence of special rules for getting a rating of 1 suggests that it's the new level, so 5 weeks for 5.
If I have Logic 5, 36 Karma, and 3 days of downtime, can I raise 3 skills from 0 to 3? At the moment, the rules say yes (I can train three skills, and the maximum increase in skills is 3 levels), but none of the examples address this point, so I'm not sure whether this is the intention. In particular, I strongly suspect that it should take at least 6 days, but at the moment the rules don't say that the time taken should be calculated for each individual step of increase, just that it is "new rating days", and the new rating is 3. Alternatively, I could spend 30 Karma and 6 months of downtime to raise the skill group to 3. I also need at least three periods of downtime. I'm not sure that the training times are intended to be quite this different. (No, I don't know why I saved up 36 Karma to do this.)
On the subject of cyberware: page 105, again: "Note that you can’t improve Physical skills or Mental attributes during the same downtime period when
you receive implants or augmentations that improve those same attributes." So can I improve Physical attributes and Mental skills at the same time? I think there must be a typo in here, but I'm not sure whether both should be attributes, or both should be both skills and attributes. Probably both attributes.
Page 105 says that an instructor reduces time by 25%. Kyra's example, page 106, says that the instructor reduces the training time by 25%. Page 105 also sends you to Using Instruction on page 141, where it says that every hit on the test reduces time by one day. I suspect that the rules on one of these two pages are an old version.
Also, page 105 says that the instructor reduces time by 25% (round down). For 6 weeks, the units are weeks, so 25% off, rounded down, is either 5 weeks (if you round down the 1.5 week reduction) or 4 weeks (if you round down the time taken). The example, however, says 4.5 weeks, which isn't rounded down.
Going by the rules on page 141, if my training time is 3 days, and my instructor gets 3 hits, do I need no time at all to learn the skill? (Do I need negative time if she gets 4 hits?) I suspect there's supposed to be a "minimum of one day" in there somewhere, but at the moment I can't find it.
