から見ると / から言うと / の上では
Judging by a criterion, rather than looking from someone's position.
～から言うと vs ～から見ると: から言うと introduces the basis you are judging on (経験から言うと). から見ると takes a vantage point, usually a person's or a group's, and reports how things look from there. Both are natural; what changes is whether the noun is a standard or a standpoint.
On paper the figures say one thing, whatever the reality is.
〜の上では vs ～にしたら: Use の上では: 計算の上では足りる. It restricts the claim to a formal or technical criterion, often hinting that reality differs. にしたら reports how a situation feels to a particular party and cannot make that on-paper reservation.
