After 2 days most of rates and reviews will be removed and it highly depends on the kind of your app, its organic traffic and usual daily rates increase, so by continuing with rates and reviews order you agree to take this risk.
For less removal try to follow these rules:
1) Do not add tons of rates and reviews for new apps or to apps with a small number of installs.
2) Do not order more than 10-15% of total number of installs in rates, use 5*+4* stars selector.
3) Do not order more than 30% of total number of rates in reviews.
Rates behavior should look like real user flow, proportionally to your app's organic traffic in the selected country and similar to your current number of rates. Appstore will remove some of rates or reviews if they find them suspicious.
Example #1: 100 installs + 15 rates + 5 reviews is good.
Example #2: 200 installs + 200 rates to new app or app without rates is bad
