My group has had two issues with this card, one real and one imagined:
(1) Multiple Calculations. In the unlikely event that more than one player draws enough of the blue deck that they each find a Calculations there is a limit of one Calculations card played per roll. (a) You can't expose a card in your hand unless you are playing it. (b) You are allowed to say you have a type of card in your hand, or even lie about it.
So, what if one player (an obvious unrevealed cylon or infiltrating leader with `cylons win') claims that they want to play a card after a die is rolled (Calculations is the only card that can change the value). Presumably this would cause the roll to change results so that something `bad' happens to the humans. If it is important then it forces any human player (actual human or infiltrating leader with `humans win') to also claim they want to play a calculations. Now, clearly, the current player must select a player to play first. If the human team is selected and plays a calculations then the cylon team gets to twiddle their thumbs because of the limit on the number of calculations that can be used.
Here's the problem. Under normal circumstances you are allowed to lie. Are you allowed to lie about wanting to play a skill card? Calculations are a limited resource, and every time the fleet jumps early at a population risk or a centurion is fired upon with the armory the cylons want the humans to use them up to convert 7s into 8s (to prevent them from becoming 6s). It's even possible (for example with Ellen/Leoben/Caprica/Adama) for a player to *know* that another player has a Calculations in their hand (also note that the three cards are uniquely tagged by numerical value if they show up in skill checks or are otherwise discarded).
(1') Similar to the above.
(non current player) ``I'd like to play a card before this skill check, it will make the skill check reckless''
(current player)``which one is it?''
(n.c.p.) ``Jury Rigged''
(c.p) ``Go ahead''
(n.c.p) plays Guts and Initiative or something else.
So the question is this: does the current players power to select the order of play extend to the card types? E.g. Players A, B, and C first have the option to play ``Jury Rigged'' then (in the same or different order) may play ``Guts and Initiative'' etc?
(2) Helo's reroll. Strategic planning presumably affects both rolls because ``it's really the same roll'' does this mean that Helo must choose to accept his roll before calculations are played?
We assume the answer to (1) is ``wow you play with a bunch of jerks that sit around thinking of pathological situations'' (we do), and (2) yes, Helo has to decide if he feels lucky with borderline rolls (he cannot choose to reroll because no one is *willing* to play a calculations even if they said they had one, nor can he reroll after letting someone play a Calculations).
