Yes they are from significant Q/POTUS deltas. However, some disagree with the #3 delta of [3].
Over at Excel thread, they think the first 5 sequence of deltas should be 15-15-5-10-5 which I can't get to fit nicely in a sequence with rule for it. A sequence should have a rule.
I will keep trying.
Let me know if you guys here have a different sequence for the five Q/POTUS deltas where Q already showed the 4th delta as [10].
I will try to work it.
