The Odds Function

TappedOut forum

Posted on Nov. 9, 2016, 1:33 p.m. by wolfdwarf

What does the Odds thing in the deck view thing actually mean? After a few turns out, the Lands' percentage becomes a 100%, does that mean to imply that there is a 100% chance of me drawing a Land on that turn??? That doesn't make sense, so I am sure I am sure that I am not understanding its function or what the Odds device is meaning to say.

From the layout I'd guess it means the probability of you drawing at least one of a specific card until turn X.

But the numbers seem really broken for that, so I'm not sure... yeaGO?

Is it broken? Doesn't seem like it's broken to me... just don't think I am reading the meaning of the numbers correctly.

As I understand it, it's the chance of having that card in hand on or before that turn, assuming one draw per turn. I suspect the 100% is rounding something like 99.999%.

Actually I rescind my previous claim it does appear to be VERY broken. Some cards have "nan%" as their odd. And although there is only 1 of every card (aside from lands, it is an EDH deck) they all have different odds...

Can someone shine a light on this?

Huh. Just looked at my EDH deck. City of Brass has an initial 70.0%, while Mana Confluence has 12.5% and Reflecting Pool has 8.9%. The numbers are also messed up for a non-EDH deck. I got no idea.

I was looking at this deck: http://tappedout.net/mtg-decks/scion-king-of-edh/card-odds/

And I noticed that Bayou is sitting at 77.8% probably because it can be searched for by multiple cards. Any of the fetch lands that target Swamps or Forest cards will grab it. I think tutor cards factor into this somehow.

But, this still doesn't explain why a card like Azorius Signet has nan% or other cards that can't be tutored up are 100% or a stupid high number.

I also noticed that the nan% never shows up below 100%. On Badlands, turn 1 is 100% then turn 2 is nan%. So, these values are going over 100% for some reason. I wish I knew what "nan" meant.

[EDIT]: Chromatic Lantern and Chaos Warp show a better progression of percentages going up steadily, reaching 100%, then going to nan%

I think nan is No Available Number or something along those lines.

NAN usually means "not a number". For example, division by zero will give you an NAN.

Missing values are specified with NA (not available).

We all know what NaN means! The question is: "how did it show up here?" or the real question is: "what the blind eternities is the Odds table suppoused to tell us?"

is this fixed?

Yeah, I think so. Just checked and the problem seems to be resolved.

On a commander deck, all the cards have the same percentage, and nan% is gone.

I really wish I knew what was causing that to happen. I know that dividing by zero could have been a cause, but there was no reason to do that. The statistics of this has no need for dividing.
