Bandwidth Estimates Calculation

#1

I feel that Bandwidth calculation is wrong.

(28B * 280 bytes) / 86400s of text => 93MB/s

  • (28B/5 * 200KB ) / 86400s of photos => 13GB/S
  • (28B/10/3 * 2MB ) / 86400s of Videos => 22GB/s

In photos and videos calculation , as there every 5 tweet is photo so it is divide by 5 and same as that every tenth tweet is video so it should divide by 10. Why it is divide by 3 too ?
