Not necessarily correct. If the forecast for PER was above Alternate Criteria and you had already passed PNR and you couldn’t carry an Alternate, you are entitled to continue and commence an approach.
It is a step by step assessment, always complying with the rules until you have the circumstances such that you can no longer comply with all of the rules.
eg. You carry 10’ hold for ATC and they tell you that it will be 16’ and you don’t have it.
