Yeah, I use the same guideline for any kind of “damage”: 1/2/3 ticks on clocks, level 01/2/3 harm, 1/2/3 levels of ship harm, etc.
Not always though: when I announced the “the Ur ruins seem to have begun opening, whoa, it looks like a jump gate is opening right in front of you!” bit, that was me telegraphing “get out or your ship will fucking die” rather than “you might take 3 hits because it’s desperate.” That’s where I don’t like feeling so very constrained by that guideline.
I’ve never even thought about the possible math ramifications of running asymmetrical racing clocks. But it felt good and scary! I’m now regretting not putting all the “you’re out of 02!” ticks against the same clock, get them sorta competing for the same resource.
