Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Shamir recovery test
This gives me a hexadecimal seed. I'm using Blockchain Common's seedtool-cli to convert the hex to bip39.

Metal storage recommendations for SSKR mnemonics
The short encoding of the SSKR shares is called byteword minimal. You can play with this tool to convert from one format to the other: https://github.com/BlockchainCommons/seedtool-cli

Splitting BIP-0039 Mnemonic
If a Shamir's Secret Sharing solution is not implemented on Ledger anytime soon then seedtool-cli is available friom Blockchain Commons which can convert your BIP-39 recovery phrase to SSKR (BCR-0011) and vice versa e.g, the following command generates SSKR shares: with k-of-n threshold 2-of-3:

Could this be the safest way to store bitcoin?
If you are familiar with linux you can go the extra mile and use a proper cryptographic tool for splitting your seed, based on Shamir's Secret Sharing Scheme to encrypt your seed to multiple parts (eg. a 3-of-5 scheme where any 3 keys decrypt the seed). You can find it here. It outputs a list of hex strings, or, alternatively, a set of mnemonic word lists that individually have no relation to your true seed but can be combined to recreate your seed.

BACK UP YOUR SEED PHRASE!
Here is a tool that let's you do it. Recommend a linux distribution on an offline computer (dig up that old laptop that takes 30 mins to boot windows and install a lightweight linux distribution).

Tyoe of Shamir's Secret Sharing used in Ledger Recover?
I am very sure it won't be. Trezor and Keystone use SLIP-49 which has some shortcomings which were improved upon by SSKR.

- Can ledger create something like Shamir backup, where users can manage the shards by themselves?

Isn't a strong bip-39 passphrase enough?
SSKR is an improvement on SLIP-39. SSKR comes with a seedtoolcli. Tezor hardware wallets use SLIP-39 if you have one of those.

SSSSS - Non-native Shamir Backup for seed phrases
SLIP-0039 is not is not round-trip compatible with BIP-0039. SSKR / BCR-0011 is based on SLIP-0039 but improves upon it by adding this compatibility.

Splitting BIP-0039 Mnemonic
Please see the discussion here: https://www.reddit.com/r/ledgerwallet/comments/ibkls4/does_ledger_have_plans_to_implement_shamir_secret/ Maybe ask here if the Ledger developers nicely if they still plan to implement Shamir's Secret Sharing, If Ledger do not implement Shamir's Secret Sharing (e.g. SSKR) then maybe consider purchasing a Trezor which implements SLIP-39. Bear in mind that SLIP-39 is not round-trip compatible with BIP-39.

Getting MultiSig Protection with a Single Hardware Wallet - Could be a better solution.... For personal vault
Or use a single hardware wallet that implements a version of Shamir Secret Sharing (SSS) e.g. SSKR and store your steel share backups in multiple locations.
