Lycoming/Honeywell have a similar count for the LTS101, requiring logging of max N1 when flown, and then a fun set of calculations to derive Ng and Np cycles. Something like total number of Ng excursions (>90% to <78% to > 90%), or Np excursions (>85% - <85% - >85%). Having taken the "lump" calculation in earlier years, it's proved to be worth recording Ng and spending a bit of time calculating Ng and Np cycles, for the better life of the engine.
Tedious, though........and hard to really keep an eye on the N1 gauge when sling loading/fire fighting
And don't bother to tell me that I could spend c$50k on an automatic bit of kit that will do it all for me, thanks
