I suggest you use alpha-numeric sustitution to guide your individual number picks. And what is this? Simple. Place winning combinations in numerical order. Assign an A for all numbers between 1 and 9, B for all numbers between 10 and 19, C for all numbers from 20 to 29; D for all numbers from 30-39, E for 40-49 and F for 50-52. This gives you an alphabetical sequence. For example, the last MM winning combination and sequence was 11.17.27.45.52/BBCEF. The one before that was 13.30.36.38.51/BDDDF.
There are 246 alpha sequences representing all possible number combinations in Pick 5/52. There are 56 sequences beginning with AA, 35 sequences beginning with AB, 20 for AC, 10 for AD, 4 for AE, 35 for BB, 20 for BC, 10 for BE, none for BF, 20 for CC, 10 for CD, 4 for CE, none for CF, 10 for DD, 4 for DE , none for DF, and 4 for EE. None for EF and FF.
If you want to work with triples in positions 1.2.3, you get 21 beginning with AAA, 15 for AAB, 15 for ABB, 10 for ABC, 6 for ABD, ... 15 for BBB, 10 for BBC ....
There are 15 sequences ending with EEF, 14 for EFF, 15 for EEE, 10 for DFF, 10 for DEF, 10 for DEE, 10 for DDE, 10 for DDD, etc
You can develop same type information for positions 2.3.4.
If you keep data for prior draws, you have inventory, history for hot sheets for alphabetical pairs, triples and individual numbers in each position, you could use these to make your final selections. For example, if you believe, or the data suggests, that the next winning combination might begin with AA in positions 1.2, AC in positions 2.3, CD in positions 3.4 and DE in positions 4.5. Your final sequence is AACDE.
If you played this sequence 5 times, you would require 10 single digits, 5 20s, 5 30s and 5 40s. The numbers to play would be taken from your hots sheets for individual numbers, overall or by position.
Since you can play 55 sets, you could play 5 sequences, using triples, beginning with AAB, 5 for ABB, 5 for ABC, 5 for BBC, 5 for BCC, 5 for BCD, 5 for CDD, 5 for AAC, 5 for ABD, 5 for ACD and 5 for BBB.
If you have this kind of data for positions 2.3.4 and 3.4.5, the final sequences can be derived.
An example, BCD has come up more often in positions 2.3.4 than any other sequence. The most frequent triple in P3.4.5 is CDE. Your hot sheets could be used to make your final selections.
Bottom line, you will be playing all of the numbers in equal proportions, according to the alphabetical sequences. Moreover, you will be playing sequences that are probable. For example, if you played a sequence beginning with CCE in positions 1.2.3, you are wasting your money. Sure anything is possible, but I wouldn't bet on it.
Likewise, playing any sequence where the last three numbers begin with a single digit would be wasteful since in MM so far, only 8 of the 242 winning combinations had an A or a single digit, in position 3.
If you don't have the data, you should make some assignments - get your 11 members to build the appropriate inventories, histories, charts, hot sheets, etc. Once you have have them, keeping them undated is simple chore.
After you make your final number selections, you should refer to your master history list, logged according to alphabetical sequences, to make sure you haven't come up with a number combination that has come up before. I have done this couple times!
Yes, lot of work keeping the data current, but better than relying on quick picks.
"Organized guess work" is a good description for this pencil and paper system.
Good luck!
By the way, I don't use sums, etc. but you could develop any charts you like.
