MH370 Search Area Recommendation | Duncan Steel

Their best estimate of position at the 00:11 ping is 37.5 S, 89.2 E, very far removed from the ATSB search areas. Their recommendation would further imply a need for another several months of bathymetric survey.
On the other hand, John Zweck, Australian Ph.D. in mathematics does an independent calculation that aligns very well with the ATSB search area. His August update:

(Note: to convert km/hr to knots, divide by 1.852)
Zweck's best estimate of position at 00:11 ping using great circle model is 98
9 E, 27:64 S and using small circle model is 99:16 E, 27:28 S.
These don't account for glide after fuel exhaustion, so are very close to the center of the ATSB Priority search area.
