dhw: How huge is “huge”? [...]

DAVID: Our current brain averages 1,200 cc+, so our enlargement of 200 cc is at 20% of the last size, quite a huge addition for a previous one lasting a couple millions of years.

Three websites that disagree:
Homo erectus Vs. Homo-Sapien: General Difference - Viva ...
https://vivadifferences.com/homo-erectus-vs-homo-sapien/

"The brain capacity was between 900 and 1200 cubic centimeters.."

I've reviewed the next one:

“So near the end of their run, when Homo erectus averaged 1,186 cc….."

Why did you leave out the rest of the paragraph:

According to research cited by scholar Richard Lynn, Homo erectus emerged 1.7 million years ago with an average brain size of 885 cc and by 200,000 years ago, their brains had increased to 1,186 cc. How does this compare to modern Western brains? Data from scholar J.P. Rushton shows that Caucasian enlisted men in the U.S. army have a mean cranial capacity of 1468 (Standard Deviation (SD) = 91) and for Caucasian women the mean and SD are 1284 and 90 respectively. From here it can be deduced that a sex-combined sample (that was 50% men, 50% women) would have a mean and SD of 1376 and 137 respectively.

Can't we have fair play in te4h quotes given? I'm disappointed.
