That looks OK now. An upstream power of 61 was not, thats well out of spec and 61 is almost full transmitting power. In practice if the downstream power is between -5 and +5 it works OK, as long as the SNR is 30 or better.

That engineer who said an upstream level of 61 is "spot on" needs retraining.
