Although it is correct that the total amount of Calcium in Jake can be perceived as 'not enough', the RDI for Calcium has been subject to discussion and change a lot for the past few years. Recently, the RDI for Calcium has been upped a lot, especially after the realisation of the importance of Calcium for woman after their menopause.
As with Vitamin D, for which the levels in Jake have recently been adjusted to the new RDI, I also expect Jake to adjust the Calcium content in the near future. Not sure, of course, but so far, Jake has always been aware of significant RDI changes and reacts to it
