Oh, so that means n is limited to 2^32 keys for each run...you could do as many runs as needed to reach desired number of generated keys.
Not sure how running a second or third time will help.... That will only create more at roughly the same distance apart as the previous run(s). Optimally, you'd want them closer together for a shorter search time.
Lol, I know you say you are new to this tool, but I do not understand what you are saying/wanting to do.
Let me break it down. Let's say you want to space all keys out at every 100; can be as close or as far apart as you want them.
So you run your first 2^32 keys as such; public key = 1, n = 2^32, range = 1:2^32*100 = n 4294967296 range = 1:429496729600, now keys will be spread out every 100 keys (429496729600 / 2^32 = 100). You follow so far?
Now let's say you want more than 2^32 keys, you want 2^33 keys. So on your next run, you would do the same, just change the public key: public key = 429496729600, n = 2^32, range = 1:2^32*100 = n 4294967296 range = 1:429496729600
SO yeah, I do not follow what you mean by "Optimally, you'd want them closer together for a shorter search time." it really makes no sense, because you can change your 2nd and 3rd runs to whatever you want, in relation to the first run, same distance, shorter distance, longer distance, etc. however, that's not the point, the point is/was, you can generate more than 2^32 keys, you just have to make multiple runs.
"Not sure how running a second or third time will help"
It helps if one wants more than 2^32 generated keys, not sure how else to explain it.
