Of note: ATL 08L/26R has HOLD markings right across the runway 400 feet in from the threshold keys at each end.

Similar to LAHSO markings (except no crossing runway in existence). No idea why (any local knowledge?).
What effect do such markings have on ASDA calculation?
NB: KATL 09R/27L has similar markings - and
also has ASDA < TORA (slightly).
