Explanation and XG's analysis

In Response To: Strange XG phenomenon (misja)

The top 3 moves of both positions result in the same posisions.
For instance 14/8 10/7 in position 1 results in the same position as 13/8 10/7 in position 2.
So I would expect that XG's analysis has the same ordering for the top 1,2 and 3 after position 1 and 2. However it doesn't:
If I give the positions after move 1,2 and 3 in position 1's analysis the names A, B and C, then in position 2's analysis they are ordered as C, A, B !
Also XG thinks there's a reasonable amount of equity between them.
Now that I'm posting this I notice that in position 1 the slotting move was not analysed at XG Roller + level, but in position 2 it was.
Should I have put the search interval bigger to prevent this from happening?
