The damage in lights,
In that case, I would not really call over 100k semi-regular. In fact, I think it's very rare, not sure how many (if any) I have seen over the years.
Looking at the database of my own bomber missions, I didn't reach 100k displayed damage even once in over 3300 bomber missions. The biggest one was a B-29 town center milking mission at 59k 'landed damage' (and about 1.8 million score points). Only 9 more missions (all B-29 strat or town milking runs) yielded 50k or more.
not sure what that would equate to in score dmg.
You can not equate that at all. There is no way to know how many score damage points someone got by looking at the 'landed damage'.
