I'm using index/match to reference account parameters on a master sheet from other sheets (sheet A, sheet B, sheet C, etc.). How well will this scale up? Can you use index/match to pull values from the master sheet to an infinite number of sheets or is there a limit to the number of times you can query the master sheet (or a limit to the number of requests made by the supported sheets A,B,C,...). I hope this makes sense. Thanks!
