I've noticed the fuel mass ratio on some of the new tanks seems off.
The little R-4 has a terrible ratio (and is incredibly huge for it's 10 liquid fuel) of 1.33:1
The R-11 is much better, but a bit off at 8.18:1
The R-12 donut is a spectacular 31:1
The classic tanks are 9:1 still it seems
(full mass:dry mass)
The RCS values are also all over the place, although that's the way it's always been (the R-10 is 5:1, the R-25 is 7:1 and the FL-R1 is 8.5).... I only mention this as I recall something about them being updated with new consistent values. Much data entry. Such error. Much ratio. Wow!
