Since I can edit the "Original Estimate" field of each story/subtask any time during the sprint (like when estimating was done on story cards, and I'm entering the estimates the day after start of sprint), I would expect the sprint start endpoint of the guidline to reflect the total of all "Original Estimate" fields' CURRENT VALUES (not shouting; just emphasizing).

I just started a 90 point sprint, entering most estimates on day 2, but my guideline says it's a 2 point sprint, so it's useless.

(I disagree with other users who want the guidline to be the guideline for work remianing. I want to know where my original estimate guideline is, so I know how far off plan discovery has driven me, so I can adapt the depth of my work and my plan to hit the end date.)

Thanks! Great tool!
