[vorbis-dev] overhead ??

[Francesco Gadaleta]

Someone could tell me the question about the question about lacing values
values of segments.
I mean i know what happens about segmentation but reading ogg specs
i didn't understand this lines:

"We simply add the lacing values for the total size; the last lacing value
for a packet is always the value that is less than 255. Note that this
encoding both avoids imposing a maximum packet size as well as imposing
minimum overhead on small packets (as opposed to, eg, simply using two
bytes at the head of every packet and having a max packet size of 32k.
Small packets (<255, the typical case) are penalized with twice the
segmentation overhead). Using the lacing values as suggested, small
packets see the minimum possible byte-aligned overheade (1 byte) and large
packets, over 512 bytes or so, see a fairly constant ~.5% overhead on
encoding space."

Pls could someone let me understand?
tnx a lot.
