Explanation needed 7% Annual physical intensity reduction - Huge change in reduction rate

Hi there was a big change from SBTi version 4.2 to V5 that from then on there was no longer the annual growth rate in Scope 3 but from then on the annual physical intensity reduction which is always 7%. Can you please tell me where there is a reason for this, preferably all the news and explanations that exist. This has triggered an increase in the reduction rate between the tools from the previous 24% to over 58% by 2030 with the new tool. Unfortunately, I can’t find anything about this publicly and this big difference is not properly described anywhere in the version descriptions either. How do you deal with this? I would really appreciate your help.
