What is the thinking behind the 100 byte excess?

A typo :) Now corrected. (Didn't make much difference in terms of speed; which surprises me.)

    That makes sense. For a 16MB file the script is only doing 1000 reads at 16K each. If each read is only reading one extra block and that extra block is always the consecutive one it probably should make only a small difference to the run time. Anyway, thanks for the clarification - thought I must have missed some clever trick.
