This is a fairly similar proposal to the one genjuro made, but with a different solution. link because mei is lazy
I think the drain time rules in their current state don't account for high star rating maps in a way that's reasonable.
I think the system currently actively discourages harder maps below 5 minutes because of the requirement to make a spread down to at least an oni (which requires more and more effort the harder the top diff is), so I think the drain time rules should follow in the footsteps of catch and add an exception for spread sizes at different drain times.
The current drain time rules are as follows
And I think they should be changed to this
I think this tackles the issues that were brought up with genjuros proposal about lower difficulties potentially being abandoned, as most maps will still be required to have them in their spreads with this change, but this opens the door to hard maps that don't need upwards of 40 minutes of drain time just to be rankable.

The current drain time rules are as follows
If the drain time of each difficulty is...
...lower than 3:30, the lowest difficulty cannot be harder than a Futsuu.
...between 3:30 and 4:15, the lowest difficulty cannot be harder than a Muzukashii.
...between 4:15 and 5:00, the lowest difficulty cannot be harder than an Oni.
...lower than 3:30, the lowest difficulty cannot be harder than a Futsuu.
...between 3:30 and 4:15, the lowest difficulty cannot be harder than a Muzukashii.
...between 4:15 and 5:00, the lowest difficulty cannot be harder than an Oni.
And I think they should be changed to this
If the drain time of each difficulty is...
...lower than 3:30, the lowest difficulty cannot be harder than a Futsuu or provide a proper spread containing at least 4 difficulties.
...between 3:30 and 4:15, the lowest difficulty cannot be harder than a Muzukashii or provide a proper spread containing at least 3 difficulties.
...between 4:15 and 5:00, the lowest difficulty cannot be harder than an Oni or provide a proper spread containing at least 2 difficulties.
