Yes Hachiman - broadly it can help to resolve TA ambiguity.
In MP, sometimes with a lot of traffic, you have to make decisions quickly and the SA contact is a good way of
resolving the ambigous contact and merging the two in TMA for a master contact.
I agree with SQs ''maybe'' - more caution may be necessary in some cases where target selection is critical
or where the contact may lie on a bearing near a potential target.
The new LwAmi 3.0, under test at present, resolves the SA bearing error so now you can get a very exact
intersection of the SA and TA tracks.
