Nah, doubt the guy is macro'ing at all. He'd have a lot more gains if he were first off. Secondly, I "lost" one point of strength, gained it back, and am now at 72 str (have lost 1 point of spirit, believe after a death as well). Mostly all I've done it seems is make bricks/mortar and architecture at the moment. Some terraforming, bit of toolcraft.
As has been stated before, it is harder to "gain" a stat point for stats already higher in magnitude (and very hard once past 90). They also decay faster, so it's harder to maintain them. Lower stats you'll see a lot more gains on, and are easier to maintain them.
