Hi,
I'm calculating external meta data size for a resource of size 976773168
total sectors.
###
Using the "first" formula (the "exact" formula, not the approximation)
gives:
[ (976773168/262144) x 8 ] + 72 = 29880.751464844 (sectors)
where 262144 = 2^18 (2 raised to the 18th power)
and 29880.751464844 sectors = 0.014248 Gb = (29880 / 2097152)
###
Now using the "approximation" formula gives
[ 465.76 Mb/32768 ] + 1 = 1.014213867 (not right)
think formula is supposed to be:
[ (465.76 Mb + 1) / 32768 ] = 0.014244385 Gb
which means the formula is:
M(Gb) ={ [ C(Mb) + 1 ] / 32768 }
Which means the result is calculated in units of Gb (not Mb), and that
the "1" is added to the total size (in Mb) before division by 32768.

Please check and let me know if you concur or if I have made mistake.
Thanks,
