Can someone please explain why 'estimated as having left' in (E) is wrong? I would appreciate if the reason provided is more helpful than 'sounds awkward' )-.

I understand that 'estimated to be' is idiomatic but looks like 'estimated as' is also idiomatic.

The core problem lies in equating the capital 'leaving' the country with 'the adding' to the strain. Adding to the strain is an effect of the 'leaving'. Hence leaving should be given the prime status and be referred by a verb. The adding part should be referred by a 'comma + ing' present participle (, adding) and not by ‘added’. Therefore, we can eliminate ABC on that score alone. Between D and E, D outplaces E with the better idiomatic use of 'estimated that'.
