Hi Marcy,
I'm not aware of what the reason is for so many early shots, but I see some are as early as 4 hours. That's really too much, unless the dose prior to the earlier shot AND the earlier shot are reduced. I think this is why you are seeing so many pinks and reds, although you are getting good nadirs sometimes.
Can I help you with scheduling? I see you are doing thins and fats on the doses, but I don't think the change is enough. As high as his dose is, you should probably be making the change in dose for an earlier shot in .25Us. So if his dose is normally 1.75U, then the reduced shots would be 1.5U.
That is for scheduling purposes only. I think it would even out his cycles better. If you know your schedule in advance, like which days you need to do earlier shots and which later shots, I can set it up for you so you know when to give how much. Just tell me what hours you would be giving the shots. Although I have to tell you, even on reduced dose, earlier by 4 hours is not advised and 3 hours earlier is pushing it. If you can make the prior shot 2 hours early than the next shot 2 hours early to even it out, that would be better.
