I think the “it retains 98% charge” quote might be misleading. Thats true for the capacity (in Ah), but not for the energy (in Wh). The report shows this clearly in the tables:

Efficiency is about 83% if my math is right (which is still good).

The report is from an independant institute from Finland, not Poland:

VTT Technical Research Centre of Finland Ltd

No? Did I claim this?

The most upvoted post has ~20 upvotes, but there are a lot of posts with 1-5 upvotes.

I‘m not worried about myself. It’s easy enough to block stuff I don’t like. All I wanted to say is that counting daily posts without excluding bots doesn’t make much sense to me.

The instance is called lemmit.online, and the most upvoted post on the whole instance is “This bot is bad for lemmy”.

One thing that annoys me about each statistic about posts is that I don’t know how many of these posts are actually interesting and engaged with.

For example, there is a specific instance that just mirrors reddit content and has barely any engagement. The bot posts mulitple posts per hour, mostly without any comments or upvotes.

It seems rather irrelevant to compare these posts to actually interesting posts with a nice discussion and a couple of upvotes.

My suggestion would be to count and plot the number of posts that have at least a few interactions.
