Why so long? Then every have already a few 490 parts and the raid gets even easyer.
A delay of 24h for the first week would be nice.
So at day 1 you can do the normal raid and prepare stuff for savage and at day 2 you can do these nice little blind runs with your static or PF.
Especially the PF raiders need to be in the first wave to get fast into the 2nd and 3rd fight to avoid a lot of casuals in the first one.
