Acute training load - very high - misleading?

My 955 is very new, so maybe it needs to "get use to me" over a little longer time than 5 days?

Yes, your acute training load will appear high during the very first days of training because the history is zero.

The green zone will eventually climb up and maybe fatten up after a couple of weeks (28 days of information are included in the chronic load green zone evaluation, 7 days for the dot line of acute load)
