Question about the mixing internals. Are internal tumblers used at ChipMixer? What does a chain analysis through ChipMixer look like?  I tried by hand, and got lost in the weeds, but most analysts will be more clever than I.  So to illustrate my question, here's what I imagine happen, but would like some confirmation.

• [1] User Bob deposits 0.0031 BTC to ChipMixer address 1BoB...wVFR
• [2] ChipMixer tumbles 1BoB...wVFR with other deposits and creates outputs of 1, 4, 32... mBTC
• [3] User Carol deposits 0.0052 BTC to ChipMixer address 1CaroL...LnGu
• [4] ChipMixer tumbles 1CaroL...LnGu with other deposits and creates outputs of 2, 8, 16... mBTC
• [5] Carol withdrawals a 4-chip and 1-chip (possibly from tumbler [2] transaction)

Is this close to correct?  Are there tumblers guaranteed between deposits and withdrawals or are one user's deposits sometimes passed directly to another user's withdrawal without a tumbler in between?  If someone made a deposit of exactly 0.001, 0.002, 0.004, could those be passed on without tumbling?

Perhaps (if internal tumblers aren't guaranteed) this is a motive for people to tip and make odd shaped deposits, so that they won't end up in someone else's future transaction history.
