Hi Carlos,
please double check:
I don't have files for N60E157, N72E057 and N77E083
I have a N64W180.hgt with a few non-zero values.
Results are in new patch.

-29m as stated in the linked page.
My understanding is that

Hi Carlos,
I'd prefer to change the default or remove the option.
@Steve: Do you remember why it was done this way? Is it still needed?
