Today August 5th happens to be the last day of the +150% Survey Point boost, which happens to be the day of the weekly reset.

So I would suggest doing the Season 2 Part 1 Hard, Season 2 Part 1 Normal/Hard Survey Point giving stages for today which grant 62 Survey Points each.

Season 1 Part 1 Hard also gives Survey Points, but only 25 Survey Points under this boost.

Basically it's not point gain x1.5, it's point gain +150%, so it's 2.5x total compared to original points or nearly 3x ish.

So if you want to maximize gains or clear this week's Survey Point shop easily, before this weeks special identification drop rate up for next two weeks until August 20 followed by a week of craft cost down until August 27 takes effect (as announced on the jp stream), this is the last day to do so after clearing everything else.

Or you could dump stamina in side story (repeat) for the maximum blue outerfes coins after doing everything else instead of Survey Points today or the special identification boost starting from tomorrow onwards, but if you haven't cleared out the Survey Point shop for this week, it's an opportunity for today only.
