Q for the OLC users: When to take the measurements?

I calculate it's speed using 3:15 method while he is still far away to spot me

Does this work for convoys as well in your experience? Sometimes the WO seems to report different ships as the closest contact, ruining this way to get the speed.

Not really, the WO does report different ships in those situations. So when I face a convoy I use the speed I got in the report (if I had received a report about that convoy). Otherwise I use the "vertical periscope line" method to determine the speed if I am in a good position..
