The 1.5 cm is all new growth from the last months worth of US assisted PE. As mentioned the first week gave quite an increase on BPSFL.
I wouldn’t say stalled, however I felt I needed to keep increasing the weights to a point I didn’t feel comfortable.
BPEL increase on 1.9cm. I needed to take several measurements to confirm this number..
Might have been some alterations in EQ as well from measurement to measurement.
I would recommend against continuing to increase the loads chasing the “optimal” strain rate. I’ve personally never seen much benefit to going beyond 3kg and that appears to be the tipping point where risk of injury accelerates rapidly.
IMO if you put in 3 days and proper heat + approx 3kg load is not producing more gains you have two options. Preferentially you would dramatically decrease your strain rate. In my experience strain rate has a higher correlation to absolute length than any other factor with the exception of achieving at least 40C temps.
Secondarily you could take an extended rest period of many weeks and allow the connective tissues to remodel themselves. If your temp is correct and your strain rate is optimal and your volume is right and you hit a wall, you gotta rest.
