Are you just trying to see how many TPs you can get on a DONE3 or do you have some certain cities that are a must ? If not the latter , YES you can do better. 2100+ is very easy. 2300 is the max ( ? ) but I am working on that as it is a slow day.

I think hnd-cmb-hkg-dps-hkg-lax-anc-lax-lir-lax-sjo-lax-doh-cmn-dxb-lhr-hnd should get you 2300 ( 13 segs at 140 and 3 segs at 160 ) if LHR-HND is credited at 160 as a list I found stated. It also stated that LHR-HKG was a 160 tp city as well. SIN is for sure but limited options for 2k+ flights out of it except to TYO.
