Always tough to say since everybody doesn't play everybody, but I think you're probably right.
On the men's side, both Dayton and VCU are clearly a step above us and Dayton won 4–3 at VCU so they're probably #1 and #2 in that order. We beat Duquesne, Fordham, Joe's, and Davidson. We missed playing Mason (canceled), SLU, and Bona. Bona and SLU are absolutely awful (as in a combined 2–30), so no seeding threats there.
For Mason, the only differeing result among common opponents was that they lost to Fordham 4–2, while we beat them 4–1. We both beat Joe's and Duquesne and lost to VCU. So it does look like we should get the #3 seed.
On the women's side, we lost 4–1 to Fordham and 4–3 to UMass. Both were undefeated in A-10 play and their match against each other was canceled, so they should be the #1 and #2, I suspect in that order based on the margins they defeated common opponents by.
We defeated VCU, Davidson, GW, Duquesne, Joe's, and Mason. We did not face SLU, Rhody, Dayton, or Bona. Bona was 0–4 in A-10 play, SLU was 0–2. Dayton was 2–1, but their wins were over cellar-dwellars Bona and Joe's, and they lost to a Duquesne squad that we beat 6–1, so we should clearly be ahead of them. (To be fair, we were Duquesne's only A-10 loss, but their 5 wins were all over bad teams.)
So it comes down to Rhody, which went 3–2 with wins over GW, Mason, and Davidson, and losses to Fordham and UMass just like us. They lost 4–0 to Fordham and 4–2 to UMass, so I think we'll come in ahead of them for the #3 seed there as well.
