I think the maxes you get at your upcoming meet will be the BEST values to use to populate the program. You may also want to take 5-20lbs off those, depending on the lift, if you're not used to very high volume and frequency. Basically you do this to give yourself some breathing room as Sheiko WILL humble even the best of men.
Also, as with any training done after a meet, you want to give yourself some down time before beginning any serious training but you already know this with your meet experience lol. So nothing or very mild general/GPP work the week after and slowly ramping up intensity over the next 1-3wks. After that you should be ready for sheiko.
