You can shift from 1st to 2nd to 3rd to 4th to 5th all within 250rpm if you like, its slow but sure sometimes i do it when I am in slow mode / no rush.
But it seems more load is Better so shifting every 500rpm increase should be more beneficial.
What I mean is you take off in first till you reach 1500rpm shift to 2nd your rpm will be about 1100 then accelerate to 1500rpm,again , shift up to the next gear repeat until your in 5th gear at 1000rpm. You should be able to accelerate from 30mph using 5th gear to what ever speed you require.
I never lug my car , its takes 900rpm to lug mine, at 1000rpm I can accelerate up to speed with no lugging from any gear.
*But* this is more my style then the 80% load theory , my technique is more like 40-50% load.. I can not handle high rpm driving for low speed driving it just seems wrong to me. It might be a mental Block.. but I think high rpm is not the right direction to go for fuel economy.
