ATPL Perf Example Query - error in CAP?

In CAP 698 there is an example for calculating the Field Length Limited TOW (Section 2 - SEP 1, Page 4).

In the worked example they derive a figure of 3530 lb which for the life of me I cannot replicate. In fact, with absolute accuracy, I obtain 3430 lb!! I wonder if the mistake is their's rather than mine?

Here is their written example:

And here is my effort:

Tackling this another way I did this with their figure of 3530 lb as the mass and worked out a TOD (to 50') as being 2700 lb.

I'd be delighted to be proved wrong here so I can move on with the the graphs but either I'm doing something wrong or their example is flawed.

All/any input appreciated, including that which proves me to be an idiot!!
