SRW will attest that in our training last year we had a rather heated argument about the rule and about making this call from the standpoint of survivability.

The rule is indeed two bases from the time of the throw.

Especially with one-umpire mechanics it is going to be damned hard to know whether that runner had indeed made it to second before the throw was made.

For survivabilities' sake, especially with a single umpire, a "rule of thumb" is: if it is the first throw from the infield (as in the scenario provided), two bases from the time of the pitch will keep you out of trouble.

More than one umpire will attest that even with two umpires, this rule of thumb will keep you out of trouble. It is generally accepted practice, and I wish the rule would be changed back to that - especially if the first throw is made by an infielder [including the pitcher (who is making a play on a batted or thrown ball) and the catcher].
