Sweep/churn my Monero balance more or less often to improve anonymity?

When I am continuously receiving small Monero payments, should I withdraw my Monero account balance (always to the same secondary XMR account of mine) more often or less often in order to ensure lower traceability of the funds?

I have read that withdrawing "account balance more often can lead to lower traceability of the funds". Is it significant? azalty@jlai.lu mentioned that "after 1 churn, there is a 1 in 16 chance (6.25%) that this transaction is yours. After 2 churns, it’s a 1 in 16x16 = 1/256 = 0.39% chance that the final output of the route is yours" But I think that what he wrote applies on a subsequent churns of "same funds" (mywalet1->mywallet2->mywallet3 = 2 churns). But when i withdraw just once per year my received balance or twice per year, does it mayke any difference (how big) in terms of anonymity/traceability?
