Harsh, but accurate…
Again, I think everyone's said it, but there's nothing special about boards. If you control your volume, intensity, and movement style, you can climb on them plenty without getting injured.
One thing to keep in mind (especially on the Moon Board) is that your ability to get volume on the boards is a function of your top-level ability. If you're a solid V8 board climber, then you have a lot of room to practice and get volume on the lower grades, because your strength and skill will drastically reduce the impact those moves have on your body. If you're just ticking the occasional V4-5 benchmark, though, you essentially have no leeway, at least on the set problems. In that case, your higher volume / practice sessions will need to use the board as a spray wall. Instead of climbing the set problems, you should just familiarize yourself with the holds: hold positions, move statically between them with open feet, that sort of thing.
Someone else mentioned it earlier in the thread as well. It's so easy to gloss over those sorts of comments and think they're just pats on the head—they're not. That is, straight up, the most valuable training I have ever done. Simply laddering holds you suck at, making sure to control every position and move statically between them, is better strength training than 99% of what people are doing in the gym. The benchmarks are fun and motivating, but climbing them isn't necessarily "training" any more than just climbing the gym sets is.
