i'm shooting 230 gr lrn @ 850'/s. the brass is landing at 5 o'clock about 15' away. is this too far and indicating a weak recoil spring?

How many total rounds are on your gun.. and on your return spring, if you know..?
Have one as well and they do fly, indicating, strong return spring, least with mine with just shy of 2k flawless rounds from NIB

though mine is a german gun made in'95, i bought it lnib and have also ~2k flawless rounds through it. i trust it most of all my handguns. are return and recoil referring to the same spring? at what point in the cycle is the brass ejected?

Fifteen feet, if you're measuring your distance accurately, seems awfully far. I have a recollection of mine throwing the brass around seven or eight feet.
are return and recoil referring to the same spring?
Yes. In fact, "recoil" spring is a bit of a misnomer, as its function is to return the slide forward. However, if it is weakened, the slide will travel to the rear much faster and eject the brass farther. Some time in the mid 1990s, Sig went to a twisted-wire-stranded, green painted spring, to better cope with "+P" ammo.
at what point in the cycle is the brass ejected?
When the slide has mostly, but not quite fully, traveled to the rear. Pull back and lock open your slide and you should be able to see the ejector (fixed blade protruding from the frame) through the ejection port. When the cartridge case hits this blade it is flipped clear.
If for no other reason than peace of mind, recoil springs are relatively cheap.
