Whittle-down goal rate is too slow for end date

@adamwolf @dreev @bee

So my whittle-down goal proj240 is currently telling me to do 17 a day, but by my calculations this will leave me one day late. It will keep me on the road, hugging the top line, but if I stay on the top line I won’t hit the target.

Here’s a pic:

By my count I have 8 days left to enter data - today is 5/6 and the end date is 5/13. And I have 154 left. So if I enter 17 a day each day I’ll be left with 154 - 8*17 = 18 still to do on the end date!

With 154 left to do over 8 days the rate should be 19, right?

Semi helpful advice:
My recommended solution to everything is to turn it into a zero-width road :sweat_smile:

I tried that before but it was too buggy to work. But maybe now the bugs have been fixed? I’ll try again.

Tried again, and it derailed me, so now I have 2 flat days. I’ll have to ask support for help

Yeah, this happened due to lanewidth, so the answer is to get into the center of the road (which is the edge of the road with no lanes) and then flip it over, for anyone else who might be wondering!

Flip it over?
:thinking:

As in, flip it to a zero-width road.

Oh I see. So if it says at least 1 day of buffer (orange) then it’s ok to “flip”?

If you’re on the dashed orange line then you should be safe – I don’t think that always corresponds to a day of buffer.

Thanks so much for the bug report and the support in working around this messy transition! Just wanted to mention that we’re actively working on stuff related to exactly this and the messy workarounds will be a thing of the past soon! In the meantime, like @shanaqui says, if you wait till you’re in the blue before shrinking your road width to zero (which is great to do; it is the future!) all should be good. Keep letting us know if not!

In the blue? I thought you just had to be in the orange…

Ah, sorry, it’s more complicated (for now! again, the beauty of YBHP is to wipe out this kind of complexity): The derailment condition is “were you in the red yesterday”. If that becomes true from changing either the road or past data, you insta-derail. So I guess it doesn’t matter what color today’s dot is. Before shrinking the road, make sure yesterday’s dot is in the blue. Thanks for clarifying that!

And again, we’re working on getting everyone transitioned to YBHP where you won’t have to think about that. And also-again, if you do convert your road to YBHP and leave it that way you should also be free of this kind of confusion, even now.

If we could do that, we wouldn’t need Beeminder - I’m too akratic and too much of an edge-skater for that.

So the good people at support helped me out and my road is now a straight line going from where I am now to the endpoint, and it says 20/day.

Look @dreev @phi, now that it’s YBHP you can really see how far behind I was despite staying on the road! I better start picking up the pace or I’ll lose $810!
:open_mouth:

I have to do 5 hours of work (20 units) in the next 8.5 hours!

I should clarify that we’re ridiculously fair-minded about this sort of thing and if this YBHP transition threw you off, just say so now and we’ll make sure the yellow brick road is adjusted to how you’d have intended it all along, etc. This is an exploding offer! No waiting till your next derailment to decide that in retrospect the YBHP thing threw you off! :slight_smile:

Lol, this is my official confirmation that the road is how I wanted it now - I’m not gonna weasel with this much at stake! Hope you don’t think I’d do that!

I just hope I don’t run into any more YBHP bugs! Hopefully everything will work perfectly now.

Ha, no, but that wouldn’t necessarily be all that weaselly if there’d been ambiguity lingering about the road fix-up. Hence the explicit confirmation that it’s now all fixed up!

We’re swatting those like, um, bugs lately; especially helpful right now to hear about even the most ambiguous/questionable possible bugs on YBHP graphs.

@dreev, am I right in thinking that non-YHBP whittle-down goals need to be set with an end date one day earlier than the actual end date, or you’d run into this problem where you edge-skated the whole way and had twice as much to do on the final day?

That sounds right. Non-YBHP goals delenda est!

PS: You wouldn’t have to do twice as much on the last day though. It would just consider you successful for staying on the road till the end even though you didn’t hit your explicit target. So, yeah, non-YBHP goals delenda extra est!

Ok @dreev I think I found another bug!

It’s telling me I have to do 19 tomorrow - but I have 134 left and 7 days to do it in. The actual rate is 19 and a seventh, which should get rounded up to 20.
