So you're saying that you can still use JLP's code for #130 as long as the range is smaller? smaller by how much? can you give me an example?
You mean like instead of
200000000000000000000000000000000:3ffffffffffffffffffffffffffffffff
you make it like
210000000000000000000000000000000:220000000000000000000000000000000
or something?
JLP's kangaroo supports a maximum range width of 125 bits. So you can split #130 into multiple chunks each with 125 bit width at max.
Chunks with 125 bit width would look like this for #130:
200000000000000000000000000000000:21FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
220000000000000000000000000000000:23FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
240000000000000000000000000000000:25FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
...
Now imagine all the years and decades wasted searching through empty sub-ranges.
