As data for 2020 is severely limited, we propose to treat it as a trial phase and are considering what, if any, of the data could be published that is useful.
Gan mai ychydig iawn o ddata sydd ar gael ar gyfer 2020, rydym yn cynnig trin y cyfnod fel treial ac rydym yn ystyried pa ddata y gellid eu cyhoeddi sy’n ddefnyddiol, os o gwbl.
