New ISC Radial scrubber question

so, is there test data on this new scrubber? Particularly anything objective that would help me better understand the benefits of a radial scrubber and in particular ISC's?

Is there an official ISC claim as to the benefits of their radial scrubber? I'm particularly interested in nailing down weather radial's are less prone to over breathing due to the greater surface area of the reactant front and greater dwell time. I"m also curious about the duration to exhaustion, which of course are two different things.

Half the reason it seems that we have to calculate such a broad buffer with an Axial scrubber is due to the chance of overbreathing during heavy exertion at depth where dwell time can suddenly drop and co2 can penetrate much deeper into the stack. At present I"m throwing out 1/3 to 1/2 of my scrubber fill (at least as indicated by the dye) as a precaution against breakthrough, which is going by recommended calculation. This requires bringing a lot more scrubber on remote international trips which is becoming increasingly expensive with respect to airline overage and when it gets down to the smaller airlines to get out to outer airlines is becoming ever increasingly problematic to take so much overall weight. If ISC's radial scrubber bears out in objective study to be more efficient and robust as well as being less prone to flooding, then it's likely worth it's weight in gold!
