That may be so, but that date conflicts with the date given by the KC shafts. The final portion of KCN appears to have a seked of 11½ palms (31.3°), and points to the upper culmination of Thuban in 2552 BCE, while the final portion of KCS appears to have a seked of 7 palms (45°), and points to the upper culmination of Al Nilam, also in 2552 BCE. This date falls within the range of dates accepted by Egyptologists for this pyramid. The date of 2450 BCE falls outside the accepted range.
