Yes, I'm aware of that, but its suitability to lunars is questionable at best. After all, this calculation in the almanac is a "fudge factor" calculation and one with dubious justification. On the other hand, it means that if you're using the Nautical Almanac data, then you better arrange your lunars in a way that is compatible with that phase "fudge factor" calculation.
