You can build a power profile from the shortest hardest test (appropriate to your event) up to the longest easiest one.
for example, a rider may do a 30s sprint test, an MMP and an FTP which gives you 3 points to plot. You then train and monitor each one to see if gains in one are affecting another and balance it with your phases and specific targets through the season/cycle.
If you (or your coach) don't understand the principles of conditioning, how or why or when to phase training then you don't need a power meter to tell you you're probably riding all the time in Z4 and most likely won't see any significant gains rather stability peppered with the odd feel good session and odd injury/niggle.
