Was it enough grav energy that it 'raced' out ahead of the rest of the BB residue and extracted everything along behind it ??
Since the BB was not an explosion away from one specific point in space, it is not possible to give a number for the sum (we don't knowhow big the universe is). But apart from that, how much gravitational waves were emitted is still extremely model dependent. In inflation models, the closer the field energy during inflation is to the plamck scale, the more grav. waves result from the quantum fluctuations of spacetime. This value can so far be almost anything, just not too high. Remember the BICEP2 announcement in 2014? They claimed to have indirectly seen grav. waves from the big bang., but were wrong. If it had been right, we'd have known that something like inflation with field energy near the planck scale has taken place (10^16 GeV to be exact, so a factor 100-1000 below, but still!). Now we don't know and it can be much smaller.
