I've got no problems with it . . .there's nothing objectively "falling apart".
My Petrel running ZHL-16C Buhlmann with GF 30/85 shows for PfcAJ's 42m/140' @ 80 min: 113 min of deco time with 5 min Deep Stop at 24m/80', 37 min at the intermediate Eanx50 stops, and 69 min at the 100% O2 stops. With the extra long intermediate stops of the RD 1:2 schedule (which is okay with me), Ratio Deco in this instance is more conservative than the Petrel Buhlmann running 30/85 GF's. . .
[Seiko Maru wreck for me was 51m max/42m ave for 55 min using RD 1:2 for 80 min deco time].
