iMX8MM - looking for DDR4 package pin delay numbers

We're doing the layout for an iMX8 Mini (MIMX8MM6DVTLZAA) board using 32-bit LPDDR4 DRAM. 

The "i.MX 8M Mini Hardware Developer's Guide", Tables 21 - 26 contain package delays numbers for many of the DDR4 signals, but appear to be missing the delays for most of the data (DQ) pins. Table 26 contains package delays for DRAM_DQ0 - DQ7. 

Where do I find the package delays for pins DRAM_DQ8 - 31?

Thanks.

Oops - found it - Table 31. Of course, 5 minutes after I posted this.
