I found this table https://www.railforums.co.uk/attachments/xlt-gif.13216/ in the forum's own fares and ticketing guide, attached to this post: https://www.railforums.co.uk/thread...ection-7-integrated-fares.70022/#post-1315636
It has 30 (not 31) for King's Cross to St Pancras. And a single figure of 35 for King's Cross to Euston (but does note that the times are not for early morning/late evening/Sunday, although it just says "extra time should be allowed" at those times without specifying how much).
