Is anyone able to locate if there is a revised threshold for exemplary performance under v4.1 of this credit? My particular project is a non zero lot line

Hello Casey,
There is no mention of Exemplary Performance related to this credit in LEED V4.1 BD+C Beta Guide 1_22_19 or online reference. So, we usually refer to the LEED v4 reference guide for missing guidance in v4.1. So, I guess exemplary performance from v4.1 (Manage 100% of rainwater that falls within the project boundary) still holds.
Thanks!

The 10/25/21 version of the v4.1 Reference Guide states that the EP is achieved with retention of the 98th percentile rainfall event (all projects) and 95th percentile rainfall event (zero lot line projects). This is on page 63 of the updated reference guide.
