As soon as Harry pulls the rabbit, DRGV will get the real run; but wait, there's more! ( as they say on late-night TV )
My theory is DRGV is Harry's "trial balloon" for his real Ace: SVAD.
He owns a bigger piece of SVAD than of DRGV, so naturally he's going to want his Box Office Boffo Payday from that one.
And DRGV gives him a "warm-up act", so to speak.
"Luck" is when preparation meets opportunity. So, don't curse your "luck" because you weren't prepared when the opportunity appeared.
