[Question] CF Leg Measurement

Hi folks, as I have recently focused on coding some procedures, I found something interesting. Give a look at VHHH BEK01D 10-3D, the CF leg required 4 things related to crs and dist. Theta, Rho, MagCrs, Dist. For the first two parts, it’s 274.3 degrees and 31NM from TD VOR. BUT, for the last two parts, it’s mysterious. 2540 is 254 degrees, which is the runway course, and it makes sense. For 0090, which means 9NM, it makes no sense. I measured from the waypoint to both sides of the runway, none of them matched. As I drew a 9 NM circle from HH421, it bearly reached the runway. See Pic1.
