Freecodecamp certificate statistics questions?

Just curious about the stats of earned certificates from the “about” section of FCC.

It says that ~2100 received the front end certificate, ~140-180 get their data/backend certificates, and only 63 got the last one.

Is this stat measuring all certificates earned for the entire time FCC has been up? I actually expected a much higher number, especially with that first certification.

I’m probably underestimating the amount of work needed to get these things (I know that last one requires LOTS of work). It was just surprising given the huge diversity FCC has here, figured there would be more certificates given out.

I actually like that it’s not just given out willy-nilly though as some participation prize.
