Again, as said before ... There must not be a bad minimum thrust to weight. SpaceX uses pintle injectors, which are generally deep throttle capable. How much deep throttle is the question.
This relative heavy landing gear would weight about 10% of the landing mass. If it is without landing gear a typical rocket stage, its drymass would weight 8-10% of the total lift-off mass, so this one would be 9% to 11% drymass. Means it needs a throttle ratio between 1:12 and 1:15. Both is no big deal for pintle injectors.
So... I don't really understand the fuzz about "how clever their engine on strategy is".
They just limit gravity losses by having a short powerful burn at the end, then a weak but long burn, with a lot of fuel being used for compensating gravity.
