Yep, it's a bit misleading. You really need to consider the table and column headings and understand what they mean:

The column "Miles Accrual Percentage" could realistically be read as "Base Mileage Earning Percentage" when considering the column "Elite Qualifying Points Per Base Mile Earned".
In the case of M class, AAdvantage base miles earned are 50% of the miles travelled and EQP's are 100% of the base miles earned which again is 50% of the miles travelled.
A lot worse is say, S class, where AAdvantage base miles earned is 50% of the miles travelled and EQP's are a 50% of the base miles earned which is in fact 25% of the miles travelled.
Taking a premium class, D, AAdvantage base mile earning is 100% of the miles travelled. An additional 25% AAdvantage miles are earned as a bonus, but these are not base miles. EQP's are 150% of the base miles earned which is 150% of the miles travelled.
A straight forward way to calculate EQP earning is to multiply the "Miles Accrual Percentage" and "Elite Qualifying Points Per Base Mile Earned" figures (ignoring any bonus miles) by the number of miles travelled.
