question

No it's ok as long as you have passing accelerated up to 6 months and a
sample on long term stability to confirm the extrapolation - meaning that if
you have 36 months real time and you want to extend to 48 you need to have a
48 month sample on stability to test and the statistical analysis of the 36
month data estimates a SL greater than or equal to 48 months

acceptable provided you have accelerated stability studies to cover the 4th

yes as long as all requirements are met 24M gets you 36 - 36M gets you 48

Verses the chart for in section 01 wording. "Accelerated (6 months OK) long
