At least from a big company perspective: This breaks down. Any set % for coding doesn't work because there are so many 'big company' problems to deal with already that take up enough of their time. Either you will end up fixing trivial stuff that a coder would have done in 10% of the time you took or you will spend too much energy on this and lose track of your actual job. Ideally I want managers who can code / have coded for a long time in their history so that they understand the software development world. But I actually want them to do time management, people management, expectations management, customer co-ordination, issue prioritization etc. IOW - Engineers can code. Engineers usually can't do those other things without flinching. Leave engineering to the Engineers and management to the Managers.
