Seems so; it was only affecting sectors 4001-9000 miles, as all the others had the correct multiples. There is a 25000-35000 entry in the ba.com page which wasn't in the MM table, so I've added that too (140/280/420 '000 miles for Y/J/F). 0.95008 is uploaded now.
Thanks for making the modification so quickly. BA oneworld awards 4001-9000 miles now show the mileage requirement that I would expect. Afraid I'm not likely to be using 420 000 miles for an award anytime soon though
