We include those links so people can see what was previously said.
First of all, some cats need more insulin than others. I believe you have seen the discussion on high dose conditions. If Pumpkin has a high dose condition it will take more insulin to get regulated. However, and this is a big one, you have to safely increase the dose so you know that the large dose is needed. Below 10'units, we only increase by 0.5 units at a time. Do you have syringes with 1/2 unit markings? Second we increase Lantus (and Levemir) based on how low it is taking kitty. You need to get some midncycle tests so we can see how a dose is working and whether there are some lows in there. It's entirely possible to see a red preshot, hit a below 50'green(human meter) and zoom back up to pink again by the next preshot. I know that because my girl did that a lot when I was first trying to get her regulated. If I wasn't getting mid cycle tests I would think she needed more insulin when in fact she was overdosed and needed less.
And please try to get some night time tests in. Many cats, including mine, would go a lot lower at night and bounce during the day, again looking like she needed more insulin but in fact needing less. Always at a minimum get a preshot test a night, so you know it's safe to give insulin. A before bed test is good information to see if kitty is going low at night. To be honest, with the amount of data on your spreadsheet and the too large size increases, I don't know if your cat is under dosed or overdosed.
If Pumpkin is happier now and more awake, that is a great sign. Hang in there, regulation is a process. You will get here.
