No, using most recent measures. Cole is used for the base as no-one seems to have done better according to what I have read. Current value for height is Lehner (and others). Internally I am not aware that anyone has replaced Petrie.

When Petrie gave his values for the base and height, the base had not been cleared of sand and the height was estimated by Petrie.

Surely it is not unreasonable to use the most up-to-date measurements available, whatever the source. If you only want one source, you need to use Petire even knowing that some of his measurements are wrong. Think!
