I parsed all the 32bit segments as the MC_SEQ_CAS_TIMING reference says but none of them has the values you mentioned.
Are these calculated with or without the value offsets (e.g CAS to read data return latency - 2).
So 19 is actually 19+2 or already with the offset 17+2? Neither seems good, it should be somewhere around 14.

By the way none of the 32bit segments seems plausible, I think there must be some other trick too.
Something with the order of the bits? (MSB-LSB?)

Too many combinations, I almost spent my whole day again on this.
