we created some stats and in fact not 70% but 80% of all -tip commits
are in linux-next right now.

Here are the full -tip commit stats (merge commits excluded):

total commits in auto-next-branches: 617
auto-branches commits in linux-next: 553
total commits in tip/auto-latest: 686
total commits in tip/master: 699

that propotion should go up to 90% on the next linux-next iteration.
(barring any problems with the new topics)
