I only gave that as an illustrative figure to help the discussion.

Virgin TV Ultra HD broadcasts at a variable bitrate and recorded averages are 10-20% lower than BT Sport 4K.

I don’t know what makes the percentages differ, but there is probably reserved space for software/apps/EPG and the rewind buffer for however many channels are running in the background.

Also how they calculate megabytes and above (one million or 1024*1024 bytes, which carries on into gigabytes).

Then how it applies rounding.

It’s only supposed to be a guide to help clear recordings and make space. The margin of error makes meaningful and accurate comparisons pointless.
