As you may have noticed, over the past week, transaction fees in the Bitcoin network have increased approximately tenfold.
On average, the recommended fee in recent days has been over 200 satoshis per byte.

Considering the size of our average transaction at 250-300 bytes, we find that we occasionally pay over 0.0006 BTC for a transfer, while charging the user 0.0003 BTC.

First of all, if you did put change in the fee, it would have been good if you tell us here also on the ANN thread so we know about it.

Secondly, you are also charging 0.4% the minimum fee, meaning the fee is being charged in percentage so doesn't that compensate for the higher tx fee too ?
It was already highlighed by many reviewers that as they add the addresses to mix, this ~~0.002 BTC~~ 0.0003 BTC, amounts too much higher and it discourages users who want to mix small amount ot Bitcoins.

Once transaction fees normalize, we will reduce the fee in our system.

From 200+ tx fee, we are now back to around 25-26 bytes,
