Incorrect LCP event size reported?

Hi,

Test results:
https://www.webpagetest.org/vitals.php?test=210718_BiDc3S_a6d03a1c80d15f5ab5834521ef30a10c&run=1

Results show LCP event is an image and is about 0.5M in size. But image is actually only about 40kB. Running image analysis confirms same.

Am I missing something?

Thanks,
Rudolf

Ahh…I think that’s confusion from not being more specific. l’m guessing you’re referring to the “size” row in the event summary? That’s the pixel size of the LCP event itself, not the image weight. I’ll add a suffix to clarify.
