Sudden SOH and CAC drop in my 24KW 2015 Leaf

I am using OVMS to keep track of my battery health. I live in Cyprus so the weather is very hot (44-45 *C in summers) In June 2022, my SOH was around 72 and the CAC (calculated battery capacity) was 48.5. In am charging till 80% unless I will be going to a long jurney. Now In September 2022 my SOH is 68 and my CAC is 44.9. Around after every Charge Cycle, my CAC will drop by 0.1. Do you guys have any idea why my leaf battery is like this? Any ideas which might fix the problem is appreciated 🙏

Battery capacity is measured in kWh, not "KW".

'22 Niro EV
'19 Bolt Premier (bought back by GM)
'13 Leaf SV w/premium (former)
'13 Leaf SV w/QC + LED & premium (lease over)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Unfortunately, it is normal for a slow decline in SOH and battery capacity over time. My 2015 was down to 8 capacity bars after 4-1/2 years and 82,000 miles when I traded it in on the 2019.
Silver LEAF 2011 SL rear ended (totaled) by in-attentive driver 1/4/2015 at 50,422 miles
Silver LEAF 2015 SL purchased 2/7/2015; traded 8/10/2019 at 82,436 miles
White LEAF 2019 SL Plus purchased 8/10/2019
