1 month only challenge, does orgasm get stronger or this is it? Advice

We have decided to be anal only for a month to see how things will go. It's day 9, wife has around 4 orgasm during anal but it's weaker than vaginal orgasm for her. She says 4 anal orgasm equals to 1.5 vaginal orgasm in terms of intensity.

We are new to anal but have had some prior experience together before deciding to do the 1 month only. She has no discomfort or pain. We are wondering if it gets stronger with time or this is pretty much it for her. We are skipping any vaginal or clit stimulation. It's also just possible vaginal is just more intense for her? We will try complete our 1 month only but would love to hear from others or advices.
