The target was met for each month between April and July 2020; however, performance has since decreased and the target has not been met for the last 14 months.
Llwyddwyd i gyrraedd y targed ym mhob mis rhwng mis Ebrill a mis Gorffennaf 2020; fodd bynnag, mae’r perfformiad wedi gostwng ers hynny, ac ni lwyddwyd i gyrraedd y targed yn y 15 mis diwethaf.
