We consider regular variation for marked point processes with independent heavy-tailed marks and prove a single large point heuristic: the limit measure is concentrated on the cone of point measures with one single point. We then investigate successive hidden regular variation removing the cone of point measures with at most $k$ points, $k\geq 1$, and prove a multiple large point phenomenon: the limit measure is concentrated on the cone of point measures with $k+1$ points. We show how these results imply hidden regular variation in Skorokhod space of the associated risk process. Finally, we provide an application to risk theory in a reinsurance model where the $k$ largest claims are covered and we study the asymptotic behavior of the residual risk.
