In the first focal plane the subtensions hold true at every magnification, so a hold is a hold wherever the zoom ring sits.

Drawn to scale from ZeroTech’s own specification sheet, and checked mark by mark by a person. This is the same geometry Harson Ballistics draws your holdover on.

Official. Same letter core as RMG (A=0.25 B=0.045 ... Z=0.014) plus DD=0.2 EE=0.3 FF=0.6 GG=0.1. Tree extends to 20 MIL (RMG stops at 10). Banner ILLUMINATED (axes and stadia printed red); colour not printed. || Rebuilt 8 Sep 2026 from rmg2-illum-specs.pdf p.2 (drawing; p.1 carries the letter table and zoom bubbles) at 400 dpi, 60 px/mil from the 1-mil stadia pitch, black+red mask, every letter checked: floating 0.045 centre dot with all four axis lines stopping 0.25 short (A); horizontal stadia +-0.5..10 at 0.5 pitch (whole 0.6 long/0.045 thick, half 0.3 long/0.014 thick - unlike RMG this sheet DOES tick +-0.5), 0.1 mrad fine scale between 4 and 5 mil both sides and between 2 and 3 mil up the vertical, numerals 2-10 both sides 0.2 tall (CC); every whole-mil crossing on the horizontal stadia and every tree row is a 0.045 dot with BOTH the hash and the axis line stopping 0.1 short (GG; line runs measured 0.8 long between whole mils); the vertical line above centre is continuous; tree rows 1-20: 0.3 crosses on whole mils and 0.06 dots on half mils, ending on a cross at +-3 (rows 1-3), +-4 (4-7), +-5 (8-9), +-6 (10-20); half-mil axis ticks between rows; numerals 0.35 tall odd left / even right; heavy bars 0.6 thick, sharp tips measured at 10.6 mil (left, right, top) reaching full thickness at 12.5, bottom bar tips at 20.5 and is full at 22.6. Earlier record had continuous axis lines through the centre, 0.045 tree dots (sheet X=0.06), 0.26-wide crosses and no stadia numerals.
Verified 8 Sep 2026 against ZeroTech's own sheet rmg2-illum-specs.pdf (RMG2 RETICLE, ILLUMINATED), page 2 drawing with page 1 letter table, rendered at 400 dpi and measured by pixel run (black+red) along both axes and rows 0.5, 8, 8.5, 9, 10, 20: scale 60 px/mil from the 1-mil stadia pitch. Checked: tree shape and 20-row count with stepped +-3/4/5/6 extents ending on crosses, hash and dot spacing including both 0.1 mrad fine scales, printed numerals (2-10 on the horizontal stadia both sides, 1-20 on the tree, none on the vertical), floating centre dot with 0.25 gaps and dotted/broken whole-mil crossings, no circles, bar inner ends (tapers 10.6->12.5, bottom 20.5->22.6), full extent of every axis.
