I'm sure I posted to this - it looks like it totally vanished!
Sorry!
The average A time for 4 months is 1hr 45 to 2hrs
https://babywhispererforums.com/index.php?topic=84884.0Although your days may vary a bit I would try to make sure that no A time goes shorter than 1hr 45 and unless you know that your LO does better on very long A times then I would make sure that no A time goes over the 2hr mark. I see some of her A times are 2hr 20 mins which may be too long at this age.
You can set the morning WU time if you prefer and keep her in her room until 6.30am daily if this suits you, then start counting the A time from 6.30 even though in reality she will have had longer if she wakes early. The later nap time should help to encourage a slightly later WU time so that you don't end up in a kind of cycle where she wakes earlier which eventually leads to an earlier BT that day which then leads to an earlier WU the next morning and so on.
I would keep extend the E times. At 4 months I would really expect her to be fine with 3hr E times, many babies (although not all) move to 4hrly E at 4 months.
For the nap extensions, personally I always prefer to start with the first nap of the day but you can choose. Babies tend to make habits quite quickly and *per nap* so whichever you choose I suggest you do the same nap each day rather than one day trying to extend nap 1 then another day switching to nap 3 etc. You can of course work on all naps at once if you have the energy for it.
Here is a link for W2S which can be helpful in extending naps as you begin to resettle with shush/pat before LO fully wakes up (so she is not fully awake and full on crying, but still sleepy). Have a look at naps option 1.
