I have visited some benchmark pages and I have noticed that:
  1) Most show the complete file sizes.
  2) None measure the ratio as bits/byte.
3) Percentage seems more common than decimal, specially when embedded in text.

This benchmark shows the inverse compression ratio in decimal in the table, but as a percentage in the text:

This benchmark shows the inverse compression ratio as a decimal fraction (.1206).

These benchmarks show the inverse compression ratio as a percentage (11.01%):

Conclusion: ratio seems more useful than bits/byte, and percentage is fine to use.


Best regards,
Antonio.
