Hey man, I would love to read more about this, can you give me the sources of where you got these numbers?
Dating the tools at the site used by these humans was first established by Archaeologist Mark Roberts to be around 500,000 years old (see Mike Pitts book, Fairweather Eden: Life in Britain half a million years ago as revealed by the excavations at Boxgrove). It is Mark Roberts that points out the difficulty using various geochronometric techniques. Bowen and Sykes (see, How Old is Boxgrove Man, Nature, 1994:751) used the racemization dating method and came to around 400,000 years. But they also note the difficulties in dating this find. The same style tools and some bone fragments found in nearby towns dated much older (around 700,000) years.
Also, it is noted in http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3566634/ that “The discovery of Acheulian hand-axes in primary context at Boxgrove, Sussex, dispelled any remaining doubt, although some of the geochronology at the site indicated an MIS 11 age (Bowen and Sykes, 1994), a view at odds with the mammalian biostratigraphy suggesting an MIS 13 age (Roberts, 1994; Roberts and Parfitt, 1999).
