In the days after [[Kaladin]]'s promotion to a captain in [[Dalinar]]'s army, [[Sigzil]] attempts to establish a baseline for how efficient Kaladin's use of a [[Surgebinding#Full_Lashing|Full Lashing]] is by measuring the amount of time it takes for a Lashing powered by the Stormlight from a single diamond chip to run out,. firstThe withstone [[Rock]] hanging from a stoneremains lashed to the wall (20for seconds),somewhere thenbetween by87 aand stone lashed without an attached weight (about 87-91 seconds). Sigzil admits, however, that without a clock to track time or a way to quantify variations in how much Stormlight is in a sphere, that thesethe measurements are imprecise.{{book ref|sa2|12}} Since arriving in [[Urithiru]], he has continued to attempt precision measurements of Surgebinding,{{book ref|sa3|46}} though it is unclear how far he has gotten.

Similarly to how spheres have become the dominant currency in the [[Physical Realm]] of Roshar, they have become prevalent in its [[Cognitive Realm]] as well - though for slightly different reasons. In the Physical Realm the value of each sphere is determined primarily by the economic value of its gemstone, as it relates to Soulcasting. In Shadesmar, however, the real currency is the Stormlight, and spheres become only as valuable as the amount of Stormlight they hold at the moment of the transaction. Presumably out of convenience, prices are still communicated in terms of the sphere denominations defined in the Physical Realm, but the gemstone type becomes irrelevant; a freshly infused diamond mark has the same value in Shadesmar as a freshly infused emerald mark - they are both "one mark of Stormlight"," even though in the Physical Realm emeralds are fifty times more expensive than diamonds.
