Hi Mostapha,
I also checked the old discussion about Big discrepancies between annual DGP calculation and DGP from image.
As far as you know, is the inaccuracy of annual DGP calculation in HB legacy caused by HB itself or caused by what Daysim is designed? Can you give me some references about how Daysim calculate the annual DGP as what is used in HB legacy?
Regards
