Some 'facts' are known but even those in dispute. I prefer to use weights and measures from LM Fast Facts PDF and work from there:
https://www.f35.com/assets/uploads/down ... 3q2015.pdfThe reason why SRVL bring back extra weight is variable is because of the variable way the WOD, sea state and other variables including potential bringback weight impact the way the SRVL is calculated. I can only point to how that is calculated without having access to the figures and of course this is under test and won't be verified until UK F-35B test ops from actual CVF sometime in 2018. And SRVLs may never be carried out for whatever reason.
The unknowns will include the amount of fuel required for minimum to land on with in VL/SRVL circumstances. This is a bunch of words without numbers so one has to guess.
There is a thread with the 'quicksilver' comment about the video of USMC F-35Bs FCLPing in 90deg F heat at YUMA telling the LSO in effect they will have approx. 6,500lbs of fuel in the hover. Now they could have more than that also because we do not know if these Bees have carried out a VL already - guessing is a fun game. I await the F-35B NATOPS with interest.

For VL: "3,000 lbs of weapons + STOVL Bringback fuel (sufficient for 2 x IFR passes with STOVL reserve)"
