If the chronicle's account of Óláfr's stake in the kingship is to be believed, it could indicate that Guðrøðr attempted to legitimise the royal succession through his canonical marriage to Fionnghuala. However, this source appears to date to the reign of Óláfr's son, Magnús, and there is reason to suspect that it source was compiled in the context of an attempt to legitimise Óláfr's branch of the Crovan dynasty over that of Rǫgnvaldr. As such, the chronicle appears to be biased towards Óláfr's line, and its account of Guðrøðr's succession may not objective. Whether the chronicle is accurate in its account of the succession is uncertain, as the Islesmen are stated to have chosen Rǫgnvaldr to rule instead, because unlike Óláfr, who was only a child at the time, Rǫgnvaldr was a hardy young man fully capable to reign as king. Furthermore, the fact that Rǫgnvaldr appears to have held power in the Hebrides at the time of Guðrøðr's death could indicate that it was Rǫgnvaldr who had been the acknowledged heir. Another possibility, suggested by the chronicle and latter correspondence between Óláfr and the English Crown, is that Rǫgnvaldr's tenure had been originally intended as temporary wardship until Óláfr was able to reign himself.
