GTM Wideip and pool persistence

Hi there , please help me understand the gtm wideip and pool persistence,

gtm wideip persistence — this tells a specific user how long you will stick with the same pool member for dns queries

gtm pool TTL: this tells the specific user, how often you would need to query the gtm for dns resolution,

for instance, if I connect to a wideip and gets a pool member as response, 10.10.10.10, assume that I have enabled wideip persistence as 3600 s, and pool ttl as 15 sec,

I will likely to get 10.10.10.10 for 1 hr, but for every 15 seconds a dns requests sends to wideip to see if the member is still active, is this accurate understanding?

please confirm
