Subject: Color Value Question

I am having trouble understanding some color definitions in "The Essentials
of Beer Style" by Fred Eckhardt. This was only brought to my attention when
I compared color values given in "The New Complete Joy of Home Brewing" to
values in Eckhardt's book. Fred gives values in a 1-10 color scale and also
in SRM values. Part of his table is:
Value SRM
1 - 1.5 1 - 2.5
1.5 - 2 2.5 - 3.5
2 - 3.5 3.5 - 5.5
3.5 - 4.5 5.5 - 10
4.5 - 5.5 10 - 18
Which is fine, no problem. But under the table, he states the color
of Budwiser as 2(1-10)/2.7 SRM. From the table, color value 2 should equal
3.5 SRM, right? What am I missing? This discrepancy seems to be consistant
throughout the book. Some places in his charts he only lists color values,
not SRM degrees.

An example that first caused me concern:
Bass Pale Ale(export) 10 degrees SRM from TNCJOHB page 49
Bass Pale Ale (E) 5.5/9.8 (color/SRM) from Essentials page 88

The SRM values match up, but his chart says 5.5 should equal 18, not 10.

Not worrying but confused,
