Multiline OBD PID Responses

General
1

Hi, I am looking for some direction on how to interpret multiline responses. As I understand the response below, it’s all from the same ECU at 7E8, and whilst I can see where B0, B1, B2 and B3 appear at the end of the first line (5D 00 2E 02), I am just wondering where B4 onwards starts, just after the 21/22/23/24 on the respective lines?

2101
7E8101C61015D002E02
7E821425661790C9200
7E822019C002E802951
7E8232E170242032A33
7E82493000000000000

This is somewhat complicated topic, but its explained in ELM327 documentation:

Thank you for steer, the explanation on page 43 is very clear.
