1% rent reduction

How are you implementing the 1% rent reduction in 19/20?

The PF article (www.publicfinance.co.uk/.../upcoming-leap-year-could-pose-challenge-housing-accountant that a rent reduction of more than 1% is required to reduce the amount tenants paid by 1% in 19/20 compared to 18/19 due to the extra day.

Reducing rent by more than 1% this will reduce the rent base in future years. Advice greatly appreciated.
