I have a run of cable where 12% is buried in ducts, the rest is on perforated tray, what are the limits on amount of cable buried when sizing cables?

See Table 4D4A of BS7671.5m of 40m run , I was looking for a formula or guide value if there is one?
Is the cable installed yet or not? Information of max demand required? The difference between Ref E & Ref D can be quite a lot of derating or larger cable sizing.I have a run of cable where 12% is buried in ducts, the rest is on perforated tray, what are the limits on amount of cable buried when sizing cables?
