Hi!
Will you be available to test today after injecting? And are you using the SLGS method? If yes to SLGS, you could have reduced after you saw Aries go under 90, both on the 6th and the 8th. Tight Regulation has you reduce when kitty goes under 50 (human meter).
158 is a safe number to shoot, especially if you will be around. One possibility is to go ahead and reduce the dose (if on SLGS and if you won't be around to test). Another option would be to give full dose, as long as you can check BGs early in the cycle and around nadir. Aries might earn a reduction, especially if you are using SLGS and reduce under 90!
ETA: if you won't be around to test enough, I'd definitely shoot .25u
