Why is the Derby/R-darter so easy to evade?

I have played with every missile. Altrough the Derby has above average agility, only being worse than the R-77 variants and mica, and being similar or slightly better than the PL-12. Its the only missile that I’ve noticed some major tracking issues.

Take a look at this video, the R-Darter should have no issue in hitting that F-16. He was kinda slow, didn’t notch, not multipathing, and the missile just failed to hit because of his simple maneuvering while heading into the missile

I have a similar thread where a Derby overled a target and failed to turn enough to connect in the end:

No. It’s the worst outside of the aim 120s in terms of turning. much worse than r77 or pl12

the darta is actually better for short range then the R77, they have more delta v while less burn time. so they have there energy way quicker. though the r77 are still better at far of-bore shots
