Recommended landscape size. Please explain

Hi.
One of the recommended landscape size is:
verts - 4033x4033
quads/section - 63
sections/component - 4
component size - 126x126
total components - 1024 ( 32x32 )

My question is, why this settings is more-recommended than:
verts - 4065x4065
quads/section - 127
sections/component - 4
component size - 254x254
total components - 256

Larger section size is recommended for bigger maps ( lower CPU cost ), also total no. of components is much lower, anyway resolution is quite similiar.
So, why then first settings are recommended?

Thanks in advance :slight_smile:

No one? Are 1024 smaller components have better performance than 256 bigger components?
