Your reply does not make a lot of sense.
So the experts (or expert yuriggg) know that 9.053 means the same as... 9022-9024-9025-9026-9051-9041-9051-9053-9054-9056-9071-9101-9103-9200-9201-9205 mmm!!
Yes it is difficult to understand. And how is a non-expert supposed to know this?
If the aim is economy, why are separate columns devoted to 8.2x, 8.3x,8.39x, 8.41.x 8.5x, 8.84x and 9.00x when all have the same applicability.
If it irritates you, why not leave the thread open so that someone more tolerant can give a sensible, logical and helpful reply?
