At JeanTate's suggestion I took numbers from crescent's post and WHO numbers for Italy's daily death rates and made a table showing daily increase/decrease ratios and associated R values assuming a generation delay of 6 days between infection and infection of others.
The important factor is the daily rate of increase/decrease. One can see in the case of Italy that R bounced around 2.5 before March 20 then dropped to just over 1 and finally below 1 on Apr 1. Keep in mind that R is a result of infections that typically occurred 3 weeks earlier.
The USA's number reflect some decrease, from around 3.5 before March 30, to around
2.3. This is still quite high but consistent with the awareness and partial social distancing in effect on March 9. I went to a restaurant about that time and it had about 2/3 the normal customers.

Because there is so much noise In day to day death variations I used the increase over a week's period but changed one day at a time. This seems to reduce noise significantly. It may be due to variations that occur naturally in reporting at different times during the week. Hence the date corresponds to the 7 day midpoint in the selected range.
Here's Italy from March 14 to Apr 3 from WHO data:
date|7 Day|daily|
Date|Deaths|Ratio|R
13-Mar|1443
14-Mar|1695|1.17|2.6
15-Mar|1872|1.10|1.8
16-Mar|2149|1.15|2.3
17-Mar|2389|1.11|1.9
18-Mar|2762|1.16|2.4
19-Mar|3384|1.23|3.5
20-Mar|3665|1.08|1.6
21-Mar|3917|1.07|1.5
22-Mar|4315|1.10|1.8
23-Mar|4527|1.05|1.3
24-Mar|4758|1.05|1.3
25-Mar|5104|1.07|1.5
26-Mar|5196|1.02|1.1
27-Mar|5305|1.02|1.1
28-Mar|5514|1.04|1.3
29-Mar|5610|1.02|1.1
30-Mar|5652|1.01|1.1
31-Mar|5752|1.02|1.1
1-Apr|5545|0.96|0.8
2-Apr|5339|0.96|0.8
3-Apr|5108|0.96|0.8
One can see the progression of Italy getting COVID-19 under control.
And here's the USA from crescent's data:
date|7 Day|daily|
Date|Deaths|Ratio|R
23-Mar|1295|x|x
24-Mar|1440|1.11|1.9
25-Mar|1919|1.33|5.5
26-Mar|2125|1.11|1.9
27-Mar|2586|1.22|3.3
28-Mar|3273|1.27|4.2
29-Mar|4075|1.25|3.8
30-Mar|4781|1.17|2.6
31-Mar|5426|1.13|2.1
1-Apr|6231|1.15|2.3
2-Apr|7033|1.13|2.1
The USA still has a ways to go but having R cross 1 somewhere around Apr 15 seems reasonable.
