Well....I'm not as fast as you. :-) But, I experience a gain of about 2s/100y from the Sim shorts. I have the Roka SimPro shorts, which are less buoyant than the Non-Pro shorts (or so I'm told). For whatever that's worth to you.
My motivation has been lacking for the last couple of days, after I learned of my good friend's passing. But, I made it back into the pool last night, and again this morning.
8/15/18 (pm):
WU:
200ez
2x50 (30s) fast
2x100 (30s) singlearm/swim
MS: 20x100 usrpt (20s) @1:40 pace: failed at #12
CD: 200ez
I was pretty happy with these. This is exactly the set that I did AFTER my last race in November last year. Same pace, same failure point. In other words, this was my peak of swim fitness last year at my A-race. So, I think I'm closer to on-track with the swim than I thought I was. I've still got 8 weeks until my A-race, so I've got some time to make some more gains.

8/16/18 (am):
WU:
200ez
2x100 (30s) single-arm / swim
MS:
3 x {
- 300 moderate (30s)
- 4x75 fast (30s)
}
CD: 200ez
I was a bit slower this morning. Not surprising since it was only 12 hours since the usrpt set. I toyed with taking an easier MS, but ultimately went with the no-pain/no-gain mentality (for better or worse). Oof...the speed change-up between the 300s and the 75s was really tough. Especially, that 3rd rep. But, I managed to get faster with each 75 in the 4-rep set.
I think I'm starting to get the hang of the faster stroke rate (or less dead-spot), when swimming faster. Intermediate pace seems to be coming around too---I can feel when I'm "gliding" and correct it, and the need to do that is getting less. But, its still hard to get the timing right at WU/CD paces.
