Template:ConvertRating

This task is unfinished This is a wiki task that requires more thought or peer review. An important issue that needs to be solved, which will appear at the top of Sega Retro:Todo until this message is removed.

A template for converting a rating, as printed in a magazine into:

• something nice to display ({{#var:displayRating}})
• a value out of 100 for use in Sega Retro averages ({{#var:score}})

it should be able to detect if a given value is invalid. Some magazines could be using multiple systems depending on context.

The user should not be expected to calculate anything.

TODO: multiple instances of the above (e.g. support "1,2,3,4" for EGM)

added text. e.g. later issues of the UK Official Dreamcast magazine, 7 = "good".
