Today we have a climate battle between an A-rated climate*, Manua Kea vs an F rated climate*, Nairobi.
Manua Kea is very sunny. There are no exact sunshine figures but there's at least 5 hours of sun per day in every month, and the total is most likely above 3000h/yr. The temperatures are also perfect because it's never too hot.
Nairobi however is way too hot for 7 months, and two of the months that aren't too hot are way too cloudy.
*Manua Kea has over 5h of sun per day in every month, and has highs below 24.4'C in every month, which means it receives an A for being perfect for every month of the year. Nairobi, however, has highs above 24.4'C in 7 months, and less than 5 hours of sun per day in two, which gives it an F because only three months per year are livable.

where are you getting sunshine stats for Mauna Kea?
I'm going off of annual direct normal irradiance from Solargis which seems to be similar to for example La Quiaca in the Andes which has 3400h of sun annually. It's a mountaintop high enough to stay above the clouds so it would make sense if it's really sunny, just like Teide observatory in the Canaries.
Provided the sun hours are correct, then yes Mauna Kea wins and it is an A and Nairobi is an F. I don't think its stupid at all as Nairobi is too hot most of the year and too cloudy in two months of the year. I don't much like the Nairobi forecast for the next 10 days. May, June and November would be a different story. And you are just blatantly copying my rating system for fun, as you don't really believe this.
Funny that Mauna Kea's record high is 24°C, it is much higher in July than any of the other months. Neither are really good climates though as it is almost never warm there even though the strong sun would make it feel warmer. It is not A* because it has no warm days/nights, that is the only thing that stops it from getting this rating.
I imagine it would be a very bizarre feeling to wear a coat wit the sun overhead!
Mauna Kea's forecast is so good in the next 10 days, sunny all the time and 2°C highs probably with snow on the ground. I always wondered about the Kenyan mountains being a perfect climate so thank you.

Manua Kea is in Hawaii, not Kenya. And Nairobi isn't uncomfortably warm at almost any time of the year. 26'C with a 90° sun isn't going to be uncomfortable, especially not with the low humidity that they've got.
And your system doesn't have a lower temperature threshold, so Mauna Kea is indeed an A in your book. It's also most likely better than San Francisco to you since as you stated that when they have the same amount of "good months", the sunnier climate wins and Mauna Kea is most likely sunnier than San Francisco.

It isn't better than San Francisco, as there is no warm weather. 26°C is uncomfortably warm to me whatever the conditions, especially given the high sun angle. My system does not have a lower temperature threshold for A climates but its still not as good as other A rated climates unless it has one month at least at 15.5°C average high or above, so you don't know the whole system. Most of the time this factor doesn't come in to play as most places with no months average high above 15.5°C are very cloudy climates. The sunnier climate doesn't always win when its A against A, that's from B to F.
I assumed Manua Kea was Kenya because you were comparing the two places and I didn't know Kenya was that close to the equator. It doesn't surprise me that there are good mountain climates in Hawaii.
