But you may be on to something. If they really have a limit of 100kgf and you have them tensioned to 99kgf you could be flirting with a catastrophic failure. Imagine if a wind gust hit at just the right yaw angle on a bladed spoke. The sail effect would bend the spoke and add 2kgf and all your spokes immediately rip out of the rim. And BAM! You're dead.
