Nah, Buffett has always stated his wealth is a handicap in terms of percentage gains because it severely limits his choices and options and that he can (and did) do far better on a percentage basis with less money. GS gave him an opportunity to invest billions in one shot, something he can't do in small caps. 42% on billions is not bad.
And that 42% will magnify more as GS rises since he basically has twice as many shares with the warrants.
