Doesn’t look to be enough time between challenges to test these before the start. Also the 1:00 am starts  are not good and go against nurses orders.
Is there any reason to believe these will run a bit faster on Linux?

I think they are mixing it up so its a good time everywhere once in a while. PG is switching their times around too.
There are at least 24 time zones around the world so one set start time does not work for everyone.
If its not a good time i just start early and get a running head start. Hit or miss.

So, any recommendations on which project to run?

CUL and WOO both have a 20% bonus. From what I am reading around CUL FFT is larger than WOO
and should take longer.
I have a couple systems running the same Xeon E5-1680 V3, and teo systems with i9-9900k and I7-9700k both 8 core Coffee lake running the same speed. I'll run one of each on each system and check the FFT size and times and see what one is best.
Being a 10 day challenge I do not think it should matter but it will give us time to see what one is best.
I may just run WOO to get a jade badge if the points per run time are close to equal.

I did a poor job on my running start but my first qualifier my be done in an hour. 12:00 pm edt.

We are currently in 12th place out of 105 teams with points on the board.
Just about five days to go as of right now. 
Figures it had to get warm out here, had to cut back some, it was too toasty in here.

Thank you Windows 10 Updates for restarting two of my Hosts last night.
I lost 10-12 hours, sucks. I forgot to turn back in Meter.
