The target was met for each month between April and July 2020; however, performance has since decreased and the target has not been met over the last 12 months.
Llwyddwyd i gyrraedd y targed ar gyfer pob mis rhwng mis Ebrill a mis Gorffennaf 2020; fodd bynnag, mae’r perfformiad wedi gostwng ac nid yw’r targed wedi cael ei gyrraedd yn y 12 mis diwethaf.
