Skip-deltas. Max of 32 jumps from zero to any revision.

And with your notional 500,000 rev repository, a max of 19 skips. Usually
much less:

rev 500,000 =
1111010000100100000, delta based on
1111010000100000000, based on
1111010000000000000, based on
1111000000000000000, based on
1110000000000000000, based on
1100000000000000000, based on
1000000000000000000, and yep u guessed it based on,
0

So thats 7 deltas from 0 to 500,000. Not bad!
