How I read the maker's table
Product page "VB-R-068 Toray 800 Carbon Fiber Aero Road Frame Hot Sale" (images uploaded Dec 2023; Bike Insights files it as VeloBuild 068, 2023; an older VB-R-068 page of 2017 on velobuild.com printed another, three-size table, 52/54/56, not this one; no model year printed, model_year null). The table's sixth column is headed "L" a second time; it continues the series (seat tube 540 after the L's 520) and the page's spec image lists "FRAME SIZE: XXS/XS/S/M/L/XL", so it is recorded as XL and the slip flagged. Rows as printed, under "SIZE IN(mm)": A "BB center to top of seattube"; B "Effectuve tio tube horizonta(l)" (sic; top_tube_effective); C "BB offset" printed with a minus sign (recorded as bb_drop, the drop); D chainstay length; E seat angle; F head angle; G front center; H head tube length; I fork offset; J reach; K stack (both to the head tube top in the drawing). No wheelbase, trail or standover printed. The XS and S print the same reach (385) with stacks 503 and 524, and the XXS and XS the same head tube (100). Spec image: full carbon Toray T800; integrated seat clamp; frame 1050g (size M, clear coat, without metal parts); headset bearings 1-1/8 in 42mm upper, 1-1/2 in 52mm lower; one pivot rim brake; rear drop 130x9 QR; BSA threaded BB (ID 41mm, width 68mm); mechanical and Di2; normal inner cable routing; max tyre 700C*25C; fork Toray T800, 380g, offset 45mm, front 100x9 QR, steerer 300mm; seatpost full carbon, 230g, length 350mm, "AERO", single bolt.
