Advanced Historical Data - How do I interpret updates?

It's safe to assume that if an update is received that conflicts with a prior update, all previously placed conflicting orders have either been matched or canceled and the remaining orders are moved to the top of the book.

For example for the two consecutive updates:

Update 1

{"op":"mcm","clk":"1282931005","pt":1584392071986,"mc":[{"id":"1.170159365","rc":[{"batb":[[0,2.2,20]],"ltp":0.0,"tv":0.0,"id":10829201}]}]}

Update 2

{"op":"mcm","clk":"1282974035","pt":1584393504411,"mc":[{"id":"1.170159365","rc":[{"batb":[[0,1.4,3.7]],"ltp":2.0,"tv":5.52,"id":10829201}]}]}

This indicates that the top of book batb is now 1.4 for selection 10829201

Please note The initial bet unmatched bet at the top of the book (2.2, 2.0) was cancelled (but no explicit update was sent).
