As it has been discussed here and here, I think the fee structure in delegation (delegated vaults) needs correction and according to the gathered voting results, I have submitted the pull request for the performance fee.
I also think, taking management fee multiple times during delegation is a behavior which needs correction but since this fee is probably the last source which covers the costs, it is probably good to have some analysis like here before applying changes to it (it seems the methods/procedures/etc. used there could also be applied here).
According to the result of analysis, if the correction of the behavior (collecting management fee multiple times during delegation) is concluded not to be tolerable, it may be decided how to compensate for it, while correcting the undesired behavior (One way, would be to increase the percentage of management fee).
If there are other opinions, it is probably good to discuss it here.
