What's the chance of a Streek Drive Super Dreadnought?

Oh, that's easy. Hitting a wall tends to slow things down quite a bit.

Heh! Got me there!

I just happened upon another item that helps to elucidate the "hyperspace band(s)" issue.

Shadow of Saganami, Chapter 8 wrote:"Helm," Helen said, "come to one-one-niner by zero-four-six at five hundred and eighty gravities, translation gradient of eight-point-six-two to h-band Zeta-one-seven. I'm uploading the waypoints now."

So we know there are at least 17 Zeta bands (unless the numbering system starts at a higher level for the higher Greek letters, sort of like a BINGO game). The translation gradient doesn't provide any units, so it must be a unit-less quantity (one in which any units would cancel each other out, such as "kilometers per kilometer")

The fact that the course she'd laid out called specifically for band Zeta-17 rather than a lower-numbered (sub-)band within the Zeta band(s) suggests either that the grav wave between the Lynx Terminus and Spindle wasn't as strong at a lower band, or perhaps even that there is variation in the effective velocity multiplier due to hyperspatial compression even between two (sub-)bands that bear the same Greek letter designation.

A courier hyper generator has a 30 seconds cycle time, a BC has a 75 sec. cycle time.

In HotQ, Trueman "hit the Iota wall a day out of yeltsin." There is 1,440 minutes in a day, so she probably went through somewhere between 2,880 and 1152 bands between the lowest alpha band and the highets Theta band.

How are the sub bands distributed? I don't know, but here is my guess:

Since there is more of a percentage spread, I would guess that the alpha band has more sub bands than than beta bands, beta has more than gamma, etc. (beta is 12 times faster than alpah, gamma is twice as fast as beta, etc.)

I would also guess that since the FTL com is 62 times faster in normal space, that the 62 times multiplyer is the speed for the lowest alpha band.

I would also guess that each sub band would have a slightly higher multiplier, so since the lowest beta band appears to be 767, that the highest alpah band probably has a multiplyer somewhere between 750-766.

Coralary: since the lowest theta band is 5,000 times faster and the lowest Iota band is 6,000 times faster, after Trueman "bounced off the Iota wall" her multiplyer was probably 5,900 times faster or more, which would translate at 60% light speed to a normal space speed of 3,540-3,599 times light spead. Of course, once she translated into the lowest Iota band, it would have taken her 8-9 hours to get up to 60% light speed.

I don't think that's right. We know that the Alpha Wall represents a single jump from 1 to 62, and there are no intervening steps at all. Between the Alpha and Beta bands is the Beta Wall, which should logically represent another major jump.

So I can see the Alpha bands ranging from 62 to some number in triple digits, but there still has to be a clear break between the highest Alpha and Beta that represents the "wall". And if the differences between sub-bands were significant, it seems DW would have said something about it somewhere.

That assumes that Truman climbed the bands at the fastest possible rate all the way to the Iota wall. I don't think that is a valid assumption. I suspect that she got up to the Eta band quickly, then started easing into the Theta band much more carefully, watching the stresses to be sure that the ship could handle it (with a very loose definition of "handle" ;) ). So this text only gives a maximum time to reach Iota, not a minimum.

I suspect that you are right about cracking the wall haveing more of a speed modifier than than a sub band translation, but I doubt that it is as steep as you think. I can see cracking a wall having 10 times the speed increase of a sub translation.

From the Zeta to Eta walls is a 20% increase in velocity. We know that there is at least 17 zeta bands. if a wall gives 10 times more volocity increase than a sub band, we are looking at a sub band of less than 1%. that is 7/10 of one percent increase per sub band 7% for cracking the wall if band zeta 17 is the top zeta band.

This same 7/10% sub band increase would mean that there could be at least 350 alpah sub bands and at least total bands Alpah through Theta.

Trueman was trying to shave every minute off the trip that she could. It is probable that she didn't cut much time off the lower, safer part of the theta bands, so I would be surprised if the average theta translation is much above double the duration of a translation in the lower bands. Even if she spend 10 times the normal translation time for each theata band, that still leaves hundreds of total sub bands, if not more than a thousand.

There are no safer parts of the Theta bands.

The way I picture it, Truman says, "We are at the top of the Eta band. Bring us up into the Theta band. Watch those generators carefully!" An hour later, "All right, the generator is still going smooth. Bring us up a bit further." An hour later, "Still going smooth. Take us up some more." Eventually, "The generator is getting a bit rough. Ease us up some more, but watch for spikes." Then, "All right, it's getting wobbly but it hasn't killed us yet. Take us the rest of the way up."

here a though, now that the Manties know about the 'streak drive science' and have a lot more knowledge about gravity then anyone else, and have a lot of hyper-scientists. Could this result in a new and deeper understanding of hyper-space, resulting in access to even more levels?

After all the streak drive was a 'brute force' approach maybe a more elegant solution could now be found?

Does anyone remember another case of numbered subbands being mentioned?
