Target times for ACT+ cartridges on GH100

For those of you using ACT+ cartridges on the GH100, what are your target times?  Mainly for an EP lab performing Ablation procedures, as this is where we will be using these ACT+ cartridges.  We currently use the ACT-LR cartridges facility wide, but the providers in EP are wanting to know the actual values during these cases instead of the "out of range high" results they are currently getting, prompting us to add the ACT+ to our test menu.  My email is aholland@catawbavalleymc.org if you would prefer to respond via email.  Thanks!
